Mattress toppers are a cost-effective way to restore an old mattress or adjust the firmness level of a new mattress. They’re made from a variety of cozy materials, including memory foam, wool, and latex. In this mattress topper roundup, we’re focusing on three extra cooling Sealy mattress toppers.

Sealy is one of the oldest mattress manufacturers in the United States, and it was recently bought by Tempur-Pedic. The Sealy brand is synonymous with high-quality bedding products, including pillows, mattress pads, and mattress toppers. The toppers we’ll cover in this review are the 3” Memory Foam Topper, the 3+1 Memory Foam Mattress Topper with a Fiber Fill Cover, and the 3″ ChillZone Memory Foam Mattress Topper.

The 3″ Memory Foam Mattress Topper with Cover

The Sealy 3” Memory Foam topper is made with SealyChill gel-infused memory foam. Gel is commonly used to cool off memory foam, which is notorious for trapping heat. Gel keeps you cool by absorbing excess heat and redistributing it across the mattress surface. This Sealy topper is swirled with blue gel, giving it a marbled look.

An Inside Look

The foam has a medium to medium-soft feel. You can easily press into the foam, which translates into excellent pressure point relief for your shoulders and hips. The 3” profile is deep enough for side sleepers and supportive enough for back sleepers. It may be a bit too soft for stomach sleepers, who need extra spinal support.

The topper comes with a removable knit cover that holds it in place. The cover is moisture-wicking, which helps to keep you dry and comfortable throughout the night.

What Makes It Great?

Sealy makes all of their products with extra comfort in mind. Here’s what we especially love about the 3 inch Gel Memory Foam Mattress Topper.

  • Adaptive: More traditional memory foams hold body impressions for longer than it takes for you to change position. The SealyChill foam responds to your movements relatively quickly. 
  • Cooling: The gel infusion in the foam prevents you from getting too hot, which promotes a deeper, more restorative sleep.
  • Cover Included: This topper comes with a cover that extends over your entire mattress, including loftier mattress styles. The cover is also antimicrobial and moisture-wicking.

Sizes and Prices

The Sealy 3” Memory Foam topper is available in standard mattress sizes. The twin is slightly wider, measuring 39” across instead of 38”. Also, note that there is no twin xl size available. This topper also has the lowest pricing of the bunch.

Size Price Dimensions
Twin $108.99 39” x 75”
Full $149.99 54” x 75”
Queen $179.99 60” x 80”
King $209.99 76” x 80”
Cal King $209.99 72” x 84”


Pros and Cons

Pros Cons
Pressure Relieving: The plush feel of the foam cushions pressure points, which can reduce or prevent back pain. This topper may have a “new foam” smell, but it should be gone after a few hours.
Temperature-Regulating: The gel infusion in the foam absorbs extra heat, so you aren’t as likely to wake up with night sweats. It’s unclear whether or not this topper is protected by a warranty.
Easy Care: The mattress cover is removable and machine washable, which improves the overall durability of the topper.


The 3+1 Memory Foam Mattress Topper with Fiber Fill Cover

The 3+1 Memory Foam Mattress Topper with Fiber Fill is a 4” topper made with 3” of memory foam and a 1” pillow top cover. The foam is the same SealyChill gel-infused memory foam used in the standard 3” Memory Foam Topper by Sealy.

An Inside Look

You can expect the same cooling properties from the SealyChill foam, although this topper won’t feel quite as cool with the pillow top cover. The cover is made from polyester and quilted with down-alternative microfiber fill. It gives the topper an extra plush feel—like sleeping on clouds.

Side sleepers are the best fit for a 4” profile, although back sleepers will also rest easy. Stomach sleepers will probably need a firmer mattress topper so their lower backs don’t arch out of alignment and cause back pain. 

What Makes It Great?

Even though the 3+1 topper has the same base layer as the 3” Memory Foam topper, there are several unique reasons why we like the 3+1.

  • Plush Feel: This topper blends the blissfully soft feel of a pillow top with cushioning, adaptive memory foam. The medium to medium-soft firmness level is easy on pressure points like shoulders and hips.
  • Stretchy Mattress Cover: The pillow top cover can stretch over the 3” topper and high loft mattresses, so you don’t need to worry about the topper slipping off of your mattress surface.
  • Cooling Gel: SealyChill foam is swirled with blue gel, which keeps the temperature of your mattress relatively neutral. Gel naturally absorbs body heat, so you don’t feel too hot or too cold.

Sizes and Prices

The Sealy 3+1 Mattress Topper and Fiber Fill Cover is offered in basic mattress sizes. It’s a little more expensive than the 3” Memory Foam topper, but you can price shop by retailer. Lots of stores price match; plus, you can use gift cards for individual stores like Target and Best Buy.

Size Price Dimensions
Twin $149.99 39” x 75”
Full $179.99 54” x 75”
Queen $199.99 60” x 80”
King $249.99 76” x 80”
Cal King $249.99 72” x 84”


Pros and Cons

Pros Cons
Dual Comfort: The 1” pillow top adds extra coziness to the 3” of responsive, gel-infused memory foam. You may notice a mild off-gassing odor for the first few hours after your topper is unboxed.
Washable Cover: The cover can be removed and machine washed, which also enables you to gently spot clean the foam. This topper isn’t available in the twin xl size.
Accessibility: Easy bed-in-box delivery allows you to simply unroll the topper on your mattress, and you’re good to go. It’s not clear whether or not Sealy’s mattress toppers are CertiPUR-US certified.


The 3″ ChillZone Memory Foam Mattress Topper

The 3” ChillZone Memory Foam Mattress Topper pairs the cooling properties of SealyChill gel-infused memory foam with Zoned PerfectChill Technology. But what does that even mean? Sealy adds an extra cooling zone across the center of the topper that responds to your body heat by cooling. 

An Inside Look

The topper comes with a thin, breathable cover that can stretch over your whole mattress. Not only is the cover antimicrobial and moisture-wicking, it can be removed and washed so it stays clean and fresh. 

The ChillZone topper is the firmest of the three we’ve covered. It’s the best match for stomach sleepers and back sleepers, who both need lots of support with a little cushion. If you’re a combo sleeper who favors your back or front, this could also be a good topper for you. Side sleepers will get some pressure relief from this topper, depending on their body type and the width of their shoulders and hips.

What Makes It Great?

The ChillZone mattress topper is designed to be great, but here’s what we especially love about it.

  • Temperature-Regulating: Not only is the whole topper infused with cooling gel, there is a heat absorbing zone across the warmest part of your body—your core.
  • Moisture-Wicking: The mattress cover prevents sweat from drenching your sheets, your pajamas, and the foam topper.
  • Supportive: Most mattress toppers are designed to soften your bed, but this one adds extra support with a touch of cushion. 

Sizes and Prices

The Chillzone Memory Foam Mattress Topper comes in five standard sizes and is a little more expensive than the rest. Most customers say it’s worth the cost!

Size Price Dimensions
Twin $199.99 39” x 75”
Full $229.99 54” x 75”
Queen $249.99 60” x 80”
King $299.99 76” x 80”
Cal King $299.99 72” x 84”


Pros and Cons

Pros Cons
Hypoallergenic: The ChillZone topper is designed with antimicrobial fibers that protect against common allergens You may need to invest in deep pocket sheets that fit over both your mattress and a 3” mattress topper.
Contouring: The foam firmly supports the delicate curves of your spine, arms, and legs. You may notice off-gassing for the first few hours after unboxing this topper.
Easy to Clean: The topper cover is removable and machine washable, which helps to keep your sleep environment clean.


Shipping and Returns

Sealy mattress toppers are available from lots of retailers, so check the product page for each one to learn more about their specific shipping and return policies. We’ve noticed that the majority of retailers provide free shipping and returns, but some may only accept returns on unused or unopened items. For example, these toppers ship for free from Target, and can be returned within 90 days of your purchase date.

Trial and Warranty

Sealy doesn’t have an official trial period for their toppers, but each retailer will likely have a return window. The Target return period is 90 days, which is pretty standard. 

Sealy mattress topper warranties aren’t very clear. Sealy works with a lot of manufacturers to make their toppers. It can be tricky to track down which manufacturer made a specific topper. Assume your topper does not have a warranty, and you’ll be pleasantly surprised if it does. One source suggested that these toppers are protected by a 1 year limited warranty, but we’re not entirely sure, and only want to present info to you that is verified.

Final Breakdown

Which one of these toppers is the best for your sleep needs? Here are our recommendations:

  • Stomach sleepers: The ChillZone mattress topper has the firmest feel, which will adequately support stomach sleepers’ spines.
  • Back sleepers: The ChillZone or the 3” Memory Foam topper will both work for back sleepers, depending on their firmness preferences.
  • Side sleepers: The 3+1 Memory Foam topper has the best cushioning and the highest profile for side sleepers.
  • Hot sleepers: According to customer reviews, the ChillZone topper sleeps the coolest.
  • Budget shoppers: The 3” Memory Foam topper is the most affordable.
