This gel swirl memory foam mattress topper is your ticket to a more restful night's sleep. Designed to add a layer of plush comfort, it revitalizes mattresses that might feel a bit too firm. With its medium comfort level, this topper adapts to your body, supporting various sleeping positions. The cooling gel technology and ventilation holes help regulate your body temperature, ensuring a breezy night's sleep.

Just like the description. I should have gotten a bit thicker size because I still do sink a little with the 2” but it has been a game changer.. Anonymous. Thu May 01 2025

So far, happy with the pad topper. Gave a few days to rest on top of the mattress in guest room. Then we put it to the test, definitely past. The 4” topper did add height to mattress ,yet sheets still fit fine. After a few nights, not sure about the cooling technology, no difference. Sleep was better. Fast shipping.. Jay. Oklahoma.

This 2 sides firmness REVERSIBLE topper is specially designed as a firm to extra firm level. It's highly suitable for people who suffer from back pain/waist pain caused by insufficient spinal support. If you are looking for a (extra) firm mattress topper that perfectly balances comfort and support, this would be the right one for you!

Great quality and value. It is firm and comfortable for side sleeper. Added plus to the firmness is the cooling gel. I took the cover off to wash it first and can not get it back on.. Julie. Clearwater, FL. Thu Jun 12 2025

The 4" Memory Foam Topper will transform your mattress from ordinary to extraordinary. Our topper features 2 inches of 2.5 lb. density temperature control memory foam layered onto another 2" of high-density support foam. The memory foam adjusts to your body temperature to help alleviate pressure points and relax muscles for a more soothing night’s sleep. Experience amazing value and softness at a fraction of the cost. Memory foam is resistant to dust mites and is naturally antimicrobial. Our topper also comes with a zippered removable cover that features a 3M Scotchgard™ moisture-wicking management protector. The protector gives the cover stain-release properties while providing moisture management for enhanced comfort and rich coziness. The cover has a ‘non-skid’ backing which locks the topper in place on your mattress. Another feature we know you’ll appreciate is that our slightly oversized topper comes in full mattress sizes to give your bed end-to-end coverage.

Fits our Cal King perfect. I little firmer than I wanted but it will probably soften up before too long. Overall my hips and shoulders feel much better in the morning. Our natural latex mattress is 20 Years old so just extended its life a bit longer for less $. Phoebe. Fortuna, CA. Fri Jun 06 2025
