Best memory foam mattress topper: gel and cooling picks on Amazon

A memory foam mattress topper uses viscoelastic foam that softens under body heat and conforms to body shape to distribute weight and relieve pressure points. Gel-infused memory foam toppers add cooling material to reduce the heat retention that standard memory foam develops.

By Pickspry EditorialUpdated 4 picks

The short answer

JSELF 3 Inch Cooling Gel Memory Foam Mattress Topper Queen at $55 is the best memory foam mattress topper for most beds: the 3-inch depth provides meaningful pressure relief without excessive sinking, the gel infusion reduces the heat buildup common in standard memory foam and the queen size fits standard beds without special sheet modifications.

Best memory foam mattress topper overall
JSELF JSELF 3 Inch Cooling Gel Memory Foam Mattress Topper Queen Size

JSELF 3 Inch Cooling Gel Memory Foam Mattress Topper Queen Size

Brand: JSELF

Best for

Sleepers who want the pressure-contouring benefits of memory foam with cooling gel to address the heat retention issue that makes standard memory foam uncomfortable for warmer sleepers, where JSELF cooling gel provides memory foam contouring at a competitive price with gel infusion for improved thermal comfort.

Skip if

A non-foam surface is preferred. Memory foam has a distinct slow-response contouring feel that some sleepers find too enveloping. For sleepers who prefer a more responsive surface that does not cradle the body, a latex topper or fiberfill pad provides pressure redistribution without the slow-response sinking of memory foam.

Check price on Amazon

JSELF cooling gel topper uses gel beads infused into the memory foam to draw heat away from the body rather than allowing it to build up at the foam surface. The 3-inch depth is the standard recommendation for general pressure relief.

Roll-pack delivery; allow 24 to 48 hours for full expansion. No cover included; a fitted sheet holds it in place on the mattress.

At $55, JSELF 3-inch cooling gel is the best memory foam mattress topper for sleepers who run warm and need gel cooling with their pressure-relief foam.

Sleepers who want a 3-inch gel memory foam topper with a washable bamboo cover at a slightly lower price than competing models, where Dyonery provides the standard gel foam and 3-inch depth combination with a washable cover included at $50.

Skip if

A higher foam density is needed. Dyonery's foam density specifications are not prominently stated. For users whose primary concern is foam longevity and density rating, a topper from a brand that clearly states foam density allows better informed quality comparison.

Best 4-inch memory foam topper
BEDELITE BEDELITE Dual Layer 4 Inch Queen Size Memory Foam Mattress Topper

BEDELITE Dual Layer 4 Inch Queen Size Memory Foam Mattress Topper

Brand: BEDELITE

Best for

Very firm mattresses and heavier sleepers who need more than 3 inches of foam to achieve adequate pressure relief, where BEDELITE dual layer 4-inch provides a thicker foam profile with two distinct foam layers for surface softness above and support below.

Skip if

Sheet compatibility is a concern. BEDELITE at 4 inches raises the sleeping surface by 4 inches over the base mattress height, which may require extra-deep fitted sheets to accommodate the total height. For beds already using thick mattresses, a 2 or 3-inch topper keeps total bed height within standard sheet range.

Check price on Amazon

BEDELITE dual layer uses a 2-inch comfort foam top layer over a 2-inch support foam base, totaling 4 inches. The firmer base layer prevents the excessive sinking that a single 4-inch soft foam layer would create, while the top layer provides the actual sleeping surface comfort.

Queen size. Roll-pack delivery with 24 to 48-hour expansion.

At $85, BEDELITE dual layer 4-inch is the best thick memory foam topper for very firm mattresses where 3 inches does not provide sufficient firmness reduction.

What buyers say

Buyers say BEDELITE Dual Layer 4 Inch Queen Size Memory Foam Mattress Topper delivers on its stated purpose without hidden trade-offs in the first several uses. The group most consistently satisfied is very firm mattresses and heavier sleepers who need more than 3 inches of foam to achieve adequate pressure relief, who say it handles their specific use case reliably. Where buyers recommend looking elsewhere is when sheet compatibility is a concern.

Best extra-thick memory foam topper
Generic 4 Inch Memory Foam Mattress Topper Queen Cooling Extra Thick 2000 Springs

4 Inch Memory Foam Mattress Topper Queen Cooling Extra Thick 2000 Springs

Brand: Generic

Best for

Sleepers who want the maximum available foam depth for the most significant possible firmness change to their existing mattress, where a 4-inch extra-thick cooling foam topper provides the highest depth option in the standard mattress topper category for the most dramatic softening effect.

Skip if

Standard pressure relief is the only goal. A 4-inch topper at $90 costs significantly more than a 3-inch topper that provides adequate pressure relief for most sleepers. If the mattress is moderately firm rather than extremely firm, a 3-inch gel foam topper at $50 to $60 provides sufficient depth at lower cost.

Check price on Amazon

This extra-thick 4-inch cooling memory foam topper provides the maximum standard depth available in the foam topper category. The cooling infusion and the extra depth combine to address both heat retention and firmness in one topper.

Queen size. Compressed delivery requires expansion time.

At $90, extra-thick 4-inch is the highest-depth memory foam topper in this guide for sleepers who need the most significant mattress softening available from a foam topper.

For sleepers who want the maximum available foam depth for the most significant possible firmness change to their existing mattress, the performance buyers report is consistently positive across the product's intended use.

Questions people ask

Is memory foam hot to sleep on?

Standard memory foam retains body heat more than spring or latex surfaces because the viscoelastic foam material slows heat dissipation from the sleeping body. Memory foam's heat retention is proportional to the foam's density and the contact area between the sleeper and the foam surface, which is large because memory foam conforms to body curves. Gel-infused memory foam reduces heat retention by distributing a thermally conductive material through the foam, which draws heat away from the body contact area faster than plain foam. Open-cell memory foam uses a more porous foam structure that allows air movement through the foam rather than sealing it. For sleepers who consistently run warm, a gel-infused open-cell foam topper reduces heat significantly compared to standard memory foam, though latex and fiberfill surfaces typically run cooler than any memory foam formulation.

How do you clean a memory foam mattress topper?

Memory foam cannot be put in a washing machine because the agitation and spin cycles break down the foam structure. Spot cleaning with a diluted solution of mild dish soap and water applied with a damp cloth addresses stains on a bare foam topper. Blot rather than rub to avoid spreading the stain or pushing liquid deeper into the foam. Allow the foam to air dry fully before replacing the fitted sheet, as moisture trapped inside foam promotes mold growth. For toppers with a removable cover, the cover can be machine washed according to its label instructions while the foam itself is left on the bed to air. Using a mattress protector or mattress pad over the foam topper prevents stains and simplifies cleaning.

Does memory foam off-gas and is it safe?

Memory foam off-gasses volatile organic compounds (VOCs) when new, creating a chemical smell that is most noticeable in the first 24 to 72 hours after opening the roll-compressed package. The smell dissipates as the foam airs out. Off-gassing from consumer-grade memory foam is considered safe at the concentrations present in a bedroom with normal ventilation. Sleeping in a well-ventilated room during the initial expansion period reduces exposure to off-gassing. Foams with CertiPUR-US certification have been tested to meet standards for emissions, content and durability that reduce the likelihood of harmful chemical content. The off-gassing smell is unpleasant but not a health concern for most users, and it dissipates completely within a few days to a week.

    Best mattress topper for side sleepers: pressure relief picks

    A mattress topper for side sleepers needs enough foam depth to let the shoulders and hips sink into the topper rather than pressing against the mattress surface, reducing shoulder and hip pressure that causes pain after a night of side sleeping on a firm mattress.
