#1Best Overall

SurChic Dual Layer Memory Foam Mattress Topper

Total thickness5 inches
Layers2-inch support foam, 1-inch cooling memory foam
CoverRemovable, machine-washable
CertificationsCertiPUR-US foam, OEKO-TEX cover
Pocket depth8 to 21 inches
Check Latest Price →

What We Like

  • Dual-layer 5-inch design for balanced pressure relief
  • Open-cell cooling memory foam reduces heat buildup
  • Deep pocket elastic skirt prevents shifting on mattress
  • Certified materials are skin-friendly and easy to clean

Trade-offs

  • At 5 inches thick, it significantly raises mattress height
  • Full expansion requires 24 to 48 hours of wait time

A five-inch dual-layer construction combines cooling memory foam with a supportive foam base, directly targeting pressure points on the shoulders, hips, and lower back for side sleepers. This design refreshes an old or firm mattress with balanced comfort and support, and the certified foam with a machine-washable cover makes for a health-conscious upgrade. It suits anyone whose mattress feels too hard but still has a solid foundation, offering a hotel-inspired comfort layer without the expense of a full replacement.

The substantial five-inch height can make fitted sheets a challenge and alter the feel of your bed frame. Compared to the four-inch Serta Dual Layer Mattress Topper, the SurChic is a full inch thicker, which adds more bulk to the sleeping surface. For side sleepers who sleep hot and need a deep cradle, this topper’s specific cooling memory foam and deep pocket design justify the added volume.

Best for: Side sleepers with a firm mattress seeking plush pressure relief and cooler sleep. Not ideal for those who dislike a significantly higher sleeping surface or need immediate use out of the box.

#2Best From Established Brand

Serta Dual Layer Mattress Topper

Serta Dual Layer Mattress Topper
Total Height4.0 inches
Comfort Layer2-inch memory foam
Support Layer2-inch pillow top
Cover FabricPremium Egyptian cotton
Warranty10-year limited
Check Latest Price →

What We Like

  • Dual-layer construction for soft pressure relief
  • Removable, machine-washable Egyptian cotton cover
  • Memory foam made in the USA
  • Includes a 10-year manufacturer warranty

Trade-offs

  • A 4-inch total height may be excessive for some bed frames
  • The pillow-top layer may feel softer than structured support foams

A dual-layer design puts two inches of memory foam directly under a two-inch pillow top, creating a distinctly soft and plush surface. This makes it a strong option for side sleepers seeking deep cushioning for hips and shoulders from a well-known brand. The removable Egyptian cotton cover simplifies maintenance, and the domestic manufacturing adds a layer of expected consistency.

At four inches thick, this Serta topper adds noticeable height to a mattress. Its dual-layer construction pairs two inches of memory foam with two inches of pillow-top material. This design provides a distinct, soft surface different from the single-material feel of a three-inch option like the Casper Sleep Essential.

Best for: Side sleepers wanting a plush, layered feel from a heritage bedding brand. Not ideal for those needing a low-profile topper or specific cooling gel technology.

#3Best Cooling Gel

CGK Unlimited Cooling Gel Memory Foam Topper

CGK Unlimited Cooling Gel Memory Foam Topper
Thickness4.0 inches
MaterialCooling gel memory foam
CertificationsCertiPUR-US & Oeko-TEX
CompatibilityAdjustable base compatible
Expansion Time24-48 hours
Check Latest Price →

What We Like

  • Generous 4-inch plush thickness for pressure relief
  • Advanced cooling gel and open-cell ventilation
  • Securely grips mattress to prevent sliding
  • Certified safe from over 350 harmful substances

Trade-offs

  • A 48-hour wait for full expansion after unboxing
  • Initial foam scent requires a well-ventilated room
  • At 4 inches, it significantly raises mattress height

A 4-inch layer of gel-infused memory foam creates a distinctively soft and pressure-relieving surface, which is the central appeal for side sleepers. This depth allows shoulders and hips to sink in deeply, promoting spinal alignment. The integrated cooling gel and ventilated design specifically target heat retention, a common complaint with standard memory foam. It transforms a firm mattress into a much softer sleeping surface, suited for those who want pronounced cushioning without overheating.

A four-inch height transforms a firm mattress into a plush surface, though it also raises the bed’s profile enough that deep-pocket sheets become necessary. This generous foam layer provides deep pressure relief by gently cradling the body, a design targeted for side sleepers. While it shares the same Queen dimensions as the Serta Dual Layer Mattress Topper, its comfort comes from a single, deep foam construction.

Best for: Side sleepers seeking a deeply plush, cool-feeling surface to alleviate pressure points on a firm mattress. Not ideal for those who prefer a firmer feel or need to minimize added mattress height.

#4Best For Hot Sleepers

DOWNCOOL Bamboo Viscose Cooling Mattress Topper

DOWNCOOL Bamboo Viscose Cooling Mattress Topper
Thickness5 inches
Cover fabricBamboo viscose & polyethylene cooling fiber
Deep pocket skirt21 inches
CertificationOEKO-TEX certified
Check Latest Price →

What We Like

  • Bamboo viscose and cooling fiber cover for instant cooling sensation
  • Full-edge elastic skirt prevents sliding on mattresses up to 21 inches deep
  • No harsh chemical odor from OEKO-TEX certified materials

Trade-offs

  • At 5 inches thick, it significantly raises mattress height
  • Requires a fitted sheet for a 21-inch deep pocket mattress

A 5-inch profile of gel and blended memory foam creates a distinctly soft, contouring surface. This thickness fits natural body curves, gently cradling shoulders, waist, and hips to release pressure for side, back, or stomach sleepers. The bamboo-derived viscose cover and breathable waffle weave actively dissipate heat, a design that directly targets night sweats.

That substantial height is the trade-off. It adds considerable bulk to your bed, which can make fitted sheets tight and alter the bed’s overall feel. For a slightly lower profile, the CGK Unlimited Cooling Gel Memory Foam Topper offers a 4-inch alternative. The DOWNCOOL, however, delivers its cloud-like softness and consistent temperature management in one integrated package.

Best for: Hot sleepers seeking a soft, pressure-relieving surface. Not ideal for those wanting a minimal change to mattress height.

#5Best For Dorms & Apartments

Serta ThermaGel Cooling Memory Foam Topper

Serta ThermaGel Cooling Memory Foam Topper
Thickness3 inches
SizeFull (53" x 75")
MaterialCertiPUR-US memory foam
Cooling FeatureThermaGel-infused
DensityHigh-density
Check Latest Price →

What We Like

  • ThermaGel infusion for cooling in warm rooms
  • High-density foam built to last four years
  • Full size fits standard dorm and apartment beds
  • Lightweight and compression-packed for easy moving

Trade-offs

  • Only available in Full size, not larger mattress formats

A 53 by 75 inch Full size makes this topper a direct fit for the standard beds found in most dorms and small apartments. The three-inch profile of high-density memory foam adds a substantial cloud-like layer without making a twin XL or full mattress feel overly tall or unstable on a basic frame. Its ThermaGel infusion is a clear design choice for stuffy rooms without strong climate control, pulling heat away from the body. This is a topper built for the specific logistical realities of student life, it’s meant to be unrolled freshman year and survive until graduation, then roll back up for the next move.

Designed specifically for a 53 by 75 inch Full mattress, this topper targets the common bed size found in dorms and apartments. Its three-inch profile provides contouring pressure relief for hips and shoulders, as described, while the ThermaGel infusion is intended to pull heat away for cooler sleep. High-density, CertiPUR-US certified foam is built to last through multiple years, and the lightweight, compression-packed design facilitates moving and storage.

Best for: Students in dorms or apartments with standard Full beds who need a durable, cooling topper that can be stored between semesters. Not ideal for side sleepers seeking the deepest possible cushioning or for those with Queen or King beds at home.
#6Best Plush Support

Sleep Innovations Dual Layer Memory Foam Topper

Sleep Innovations Dual Layer Memory Foam Topper
Total thickness4 inches
Top layer1 inch fluffy pillow top
Support layer3 inch cooling gel memory foam
CoverRemovable and washable
CertificationCertiPUR-US certified
Check Latest Price →

What We Like

  • Dual-layer 4-inch profile for deep cushioning
  • Cooling gel memory foam for pressure relief
  • Removable, fitted-sheet-style cover for easy care
  • Hypoallergenic materials and a 10-year warranty

Trade-offs

  • A 4-inch height can make fitted sheets difficult
  • The pillow top is integrated, not a separate pad
  • At 24.2 pounds, it is substantial to move and place

Sleep Innovations’ 4-inch topper combines a 3-inch layer of cooling gel memory foam with a 1-inch pillow top cover, creating a deep and plush sleeping surface. According to the manufacturer, this design offers plush support for all sleep positions, not just side sleeping. The cooling gel is intended to address heat retention, while the removable, washable cover simplifies maintenance for a topper of this thickness.

The topper’s 4-inch total height is a substantial addition to any mattress, which may require sheets with deeper pockets. Among the listed products, it shares this height with the Serta Dual Layer and CGK Unlimited toppers in queen size. The Sleep Innovations model uses a specific dual-layer construction of gel foam and a pillow top. This integrated two-part design aims to provide both conforming support and an immediate soft feel.

Best for: Shoppers looking for a thick, dual-layer memory foam topper with a removable cover and a plush feel.

#7Best Adjustable Comfort

BEDELITE Egg Crate Memory Foam Topper

BEDELITE Egg Crate Memory Foam Topper
Thickness3 inches
DesignDual-layer flip
CoverRemovable bamboo viscose
Corner strapsWide elastic
Expansion time48-72 hours
Check Latest Price →

What We Like

  • Two firmness options in one topper
  • Removable, machine-washable cover
  • Secure fit with elastic straps and silicone strips
  • Egg crate side is soft for side sleepers

Trade-offs

  • Thinner profile than many 4- or 5-inch competitors
  • Requires up to three days to fully expand before use

A 3-inch topper with a dual-layer flip design lets you switch between a soft, pressure-relieving egg crate surface and a firmer, flat foam side. This makes it a genuinely adjustable piece of bedding, ideal for side sleepers who want a cushioned hug one night but might need more stable support the next. The removable, washable bamboo cover and anti-slip anchoring system mean it’s built for easy maintenance and stays in place, which is a relief for anyone tired of wrestling a bunched-up pad.

The BEDELITE topper offers a dual-layer flip design, giving you two comfort options in one. Its egg crate side provides a softer, more elastic feel, while the flat side is firmer and more stable. This allows sleepers to switch between a cushioned hug and firmer support as their sleep style changes.

Best for: Side sleepers who want the option to flip to a firmer feel. Not ideal for those seeking the deepest possible cushion from a single surface.

#8Best 2-in-1 Design

ChiXpace Dual Layer Egg Crate Topper

ChiXpace Dual Layer Egg Crate Topper
Layers2-inch gel memory foam + 2-inch pillow top
Surface design7-zone egg crate structure
Cover material35% bamboo rayon, 65% polyester
Check Latest Price →

What We Like

  • Two independent layers for adjustable softness
  • Egg-crate foam targets pressure points for side sleepers
  • Removable, machine-washable cooling cover
  • Deep elastic skirt secures it on most mattresses

Trade-offs

  • Requires 24-48 hours to fully expand after unboxing
  • Initial new foam smell may be present

A 2-inch pillow top layered over a 2-inch zone-cut memory foam results in a distinctly plush surface. Side sleepers will notice how the egg-crate pattern concentrates cushioning under shoulders and hips, which can ease joint pressure. The dual-layer design means you can use the quilted pad alone for a slight softness boost or combine both for a deeper, plusher feel. This adjustability suits someone who wants to fine-tune their bed’s comfort level over time.

The ChiXpace topper requires a planning window, as its compressed memory foam needs up to 48 hours to fully expand to its 4-inch height. This two-day wait contrasts with simpler single-layer toppers that may rebound faster, but the dual-layer design delivers a distinct combination of zoned support from the egg-crate foam and a soft, quilted surface.

Best for: Side sleepers seeking a highly adjustable, plush surface with targeted pressure relief. Not ideal for those who need a topper ready to sleep on immediately or who have low-profile bed frames.

#9Best Easy Setup

Casper Sleep Essential Memory Foam Topper

Casper Sleep Essential Memory Foam Topper
Thickness3 inches
Foam typeMemory foam
CoverSoft-knit included
Weight16.7 pounds
SetupUnbox and unroll
Check Latest Price →

What We Like

  • Breathable foam design for airflow
  • Soft-knit cover adds immediate coziness
  • Pressure-relieving memory foam comfort
  • Simple unbox-and-unroll setup process

Trade-offs

  • Weighs 16.7 pounds for handling.
  • Three-inch thickness provides a moderate cushion.

The Casper Sleep Essential topper adds three inches of pressure-relieving memory foam to any mattress, which provides a straightforward comfort upgrade without complex setup. Its included soft-knit cover means it is ready to use immediately after unboxing, fitting scenarios like guest beds or dorms where simplicity is valued. The foam is described as responsive and breathable, which helps keep air flowing during sleep.

That simplicity comes with a trade-off in specialized features. The single foam layer provides a uniform softness, but it doesn’t offer the targeted zoning or advanced cooling of a dual-layer topper like the CGK Unlimited. For a side sleeper whose primary need is an uncomplicated, breathable softness boost, this delivers. If you’re looking to completely transform an old mattress with deeper contouring, you’ll want more inches and layers.

Best for: A queen bed needing a straightforward comfort addition with a breathable, soft-knit cover. Not ideal for a bed requiring cooling gel infusion or a thickness greater than three inches.
#10Best Shredded Foam

Qocismile Shredded Memory Foam Topper

Qocismile Shredded Memory Foam Topper
Thickness3 inches
Fill MaterialShredded memory foam
Cover FabricViscose and polyester
Side Panels3-inch air-mesh
Pocket DepthUp to 24 inches
Check Latest Price →

What We Like

  • Shredded foam offers a uniquely soft, conforming feel.
  • Breathable air-mesh sides enhance ventilation for cooling.
  • Deep-pocket skirt provides a secure, non-slip fit.
  • OEKO-TEX and CertiPUR-US certified materials.

Trade-offs

  • A 3-inch profile significantly raises mattress height.
  • Shredded foam may feel less uniformly supportive than a solid slab.

A 3-inch layer of shredded memory foam produces a distinctly plush, cloud-like surface that deeply conforms. This is a clear match for side sleepers seeking pressure relief at the shoulders and hips. Its design prioritizes a soft, forgiving feel over firm support, and the breathable side panels add a genuine cooling element often missing in basic toppers. This makes it a straightforward solution for someone with a mattress that’s simply too firm.

The shredded memory foam filling creates a cloud-like, lighter feel compared to solid foam designs. This approach prioritizes a soft and adaptable pillow-top sensation over a deeply contouring support structure, which suits sleepers who want a plush surface that easily adjusts as they move.

Best for: Side sleepers who prioritize a supremely soft, pressure-relieving feel and need extra cooling. Not ideal for those who prefer a firm, solidly supportive surface or have limited clearance for a taller bed.

How We Evaluated Soft Mattress Toppers For Side Sleepers

Our research focused on manufacturer specifications, expert recommendations, and consistent themes in owner feedback. We prioritized thickness and material for pressure relief, cooling features for hot sleepers, and secure-fit designs to prevent shifting. We also considered warranty length and material certifications as indicators of durability and safety.

A key criterion was thickness, as side sleepers often need a topper thick enough to cradle the shoulders and hips. We looked for models in the 3- to 5-inch range. Cooling performance was another major factor, examining features like gel infusions, open-cell foam, and breathable covers to address a common complaint among side sleepers.

This guide is based on published product specifications and descriptions. Individual comfort and the exact feel of materials are subjective experiences that can vary. The information provided is intended as a researched starting point for your search.

What To Look For In Soft Mattress Toppers For Side Sleepers

Selecting the right soft topper involves more than just picking the plushiest option. You must consider how it will interact with your existing mattress and your specific needs as a side sleeper.

Look for a topper at least 3 inches thick with pressure-relieving materials like memory foam or soft latex. Ensure it has a secure fit and cooling properties if you sleep hot.

Thickness And Material

A topper’s thickness directly impacts its ability to cushion your pressure points. For side sleepers, a 3-inch profile is often the minimum for noticeable relief, with 4- to 5-inch models offering deeper contouring. The material defines the feel: memory foam conforms closely and relieves pressure, while latex offers a bouncier, more responsive softness. Understanding the soft vs firm toppers comparison can help clarify your preference. Our research on foam mattress toppers shows they are a popular choice for this cushioning effect.

Cooling Features

Soft materials, especially memory foam, can retain heat. Effective cooling technologies are crucial for comfort. Look for open-cell foam structures, gel infusions, or phase-change materials woven into the cover. Breathable fabric covers, like bamboo viscose or cotton, also promote airflow. These features are a primary focus for side sleepers, who often need a cooler sleep surface, when choosing the best mattress topper.

Secure Fit And Ease Of Care

A topper that slides off the bed defeats its purpose. Deep-pocket elastic skirts, often designed for mattresses up to 21 inches thick, provide the most reliable grip. Some models include corner straps or silicone strips for extra security. For maintenance, a removable, machine-washable cover is highly convenient, protecting your investment and simplifying cleaning. This is a key consideration when choosing a mattress topper.

  • Measure your mattress depth before buying to ensure the topper’s pocket or skirt will fit.
  • Check the expansion time; some foams require 24-48 hours to fully decompress.
  • Verify material certifications like CertiPUR-US or OEKO-TEX for peace of mind regarding off-gassing and safety.
  • Consider the total height added; a 5-inch topper may make your bed significantly taller.
  • If you have a firm mattress, a thicker, dual-layer topper may provide the softening effect you need.

The best soft topper for you adds plush comfort without compromising support for your spine.

Frequently Asked Questions

Which is the softest mattress topper?

Softness is subjective, but toppers designed with plush memory foam or shredded foam constructions often provide the deepest, most conforming soft feel. Models like the Qocismile Shredded Memory Foam Topper or the SurChic Dual Layer are built for significant cushioning. For a wide selection of very soft options, you can explore dedicated guides to plush mattress toppers.

Can a mattress topper make a mattress softer?

Yes, a soft mattress topper is specifically designed to add a comfort layer that makes a firm mattress feel softer. It provides a plush surface for your body to sink into, which can alleviate pressure on the shoulders and hips for side sleepers. This is the core function of mattress toppers designed to make a bed softer.

Which is the best mattress topper for side sleepers?

The best topper for a side sleeper balances plush cushioning for pressure points with enough support to keep the spine aligned. Our top pick, the SurChic Dual Layer Memory Foam Topper, excels here with its dual-layer design. Other excellent choices include the cooling-focused CGK Unlimited and the adjustable BEDELITE Egg Crate Topper.

What is the number one rated mattress topper?

Based on our research, the SurChic Dual Layer Memory Foam Mattress Topper is a top-performing option. It consistently meets the key needs for side sleepers: substantial thickness for pressure relief, integrated cooling features, and a secure fit to prevent shifting during the night.

What thickness of mattress topper is best for side sleepers?

A thickness of 3 to 4 inches is generally ideal for side sleepers. This range provides enough material to cradle the shoulders and hips without creating an unstable sleeping surface. Thinner toppers may not offer sufficient pressure relief, while very thick 5-inch models can significantly raise the bed height, which may not suit all bed frames or sleepers.

The Bottom Line

For most side sleepers seeking to soften a firm mattress, the SurChic Dual Layer Memory Foam Mattress Topper is the best overall choice, offering balanced pressure relief and cooling in a secure, durable package.

If you are on a budget or need a topper for a standard dorm bed, the Serta ThermaGel Cooling Memory Foam Topper is a smart pick. Hot sleepers should strongly consider the DOWNCOOL Bamboo Viscose Cooling Mattress Topper for its instant cooling sensation.

Ultimately, the most important factor is choosing a topper thick enough to cushion your pressure points, ensuring your shoulders and hips are properly supported for a comfortable night’s rest.
