BioPEDIC 4-Inch Twin-XL Size Mattress Topper, iCOOL Tech and Gel Swirl Medium Plush Memory Foam Mattress Topper, CertiPUR-US Certified, White, Twin-XL Size (80" L x 39" W x 4" H)

I bought this to split a queen in half. My partner likes his bed hard, and I would wake up with my back & hips absolutely killing me every morning. This worked great. It is so much support & cool. It completely hugs your body offering support & cushion everywhere. It didn’t smell like the other comments said at all, and I am sensitive to smell. I did let it air out for ~12 hours to inflate. It does require larger sheets, like the extra material to grab because it is thick. Will be ordering some new sheets to go alongside this. Great solution to a problem that could’ve led us to buying a new bed!! THANK YOU! ⭐️⭐️⭐️⭐️⭐️

My mattress is wearing out, and my body is feeling it, having extreme aches when getting up in the morning. In order to avoid buying a new bed, I thought I'd try this first. I got the 2" foam and it fit perfect. I no longer have pain and am sleeping better. Feels like a whole new mattress and a lot cheaper!!

The cooling gel is good not to cold really very nice. It if firm enough to keep my back from hurting and the softer than I thought it would be.!

The 4” memory foam mattress cover is a perfect fit for my twin size futon when laid open as a bed. It makes for a very comfortable sleeping situation. It improves the live ability of my one bedroom apartment. I highly recommend it to anyone who wants it get a better way to get a good nights sleep

My boyfriend and I purchased this in October. It took us some getting used to since we had never had a mattress topper like this before. But it’s very comfortable and helps us with our sleep. It came packaged well and it expanded perfectly with no issues. Accurate thickness.

I gave it two attempts. First time, 3 nights. Took it off-- my husband and I kept sinking way in. For a 2 inch foam, one would think you wouldn't get such a sinking feeling. A few weeks later, pulled it out the closet and decided to give it another shot. On the 3rd day, I literally woke up, got up, peeled the pad off the bed, and walked it out to the garage so my husband could take it to the dump. I'm 5-8, 165lbs. I don't know how the thing sucked me in so much.

I’m not gana say it’s not good, it’s a nice topper an for those say’n it doesn’t fully expand all you had to do was get a blow dryer, hold it to the topper an it’ll immediately fluff right up 🙄 if you’re look’n for a firmer topper then this isn’t for you, overall it’s very comfy it’s jus on the softer side.

I have had the topper for 4 days now, unpacked, and it's still not fully expanded. I bought the 2" queen size. I feel like the places that have expanded will be nice and soft. I am surprised that it is taking so long to expand. Should I continue to wait, or could it be defective? It seems to be a little fuller each day, but some places are only about a half-inch thick so far. It's currently rather uneven. Fortunately, it's for an extra room with a very firm mattress that we aren't using just yet. I had hoped for better results.

I purchased this for my parents for Christmas.. they said they have never slept so well..also they said " it's like sleeping on a cloud"

Best topper ever made!!

picture on amazon misleading. shows blue almost cooling gel like cover on the foam. it is actually more of a dark green colour shot through the foam, not a blue cooling gel like in cooler gel packs.the pad is comfortable and does seem to spread the heat a little bit around the foam rather than concentration it right where your body touches pad. odd smell has not dissappated after a month. not terrible but i am not sensitive to it. overall, i like the pad. it is comfortable. i think i would consider buying again.

First of all the expansion time was very long. Sleeping on it for the first couple of months it was great but then it started to rip and tear after only a couple of months. Like the material had lost all of its elasticity. The warenty requires a UPC code and I cannot find that anywhere in my oder details. So it's useless that you can't even get help with that. Can't return because it has been so long. Save yourself time and money and buy something else unless you like sleeping essentially flat because it loses support within months. I'm rethinking purchases such as these from Amazon sadly. I'm at a loss and stuck without any solutions.

Small crack in corner that I'm afraid will grow. Comfortable otherwise and cool colors.
