I had a too-thin memory foam mattress (I cheaped out, oops), this saved it. I added a fluffy mattress pad over top before the sheets, et voilá: soft, supportive and non-sweaty. It does smell strongly for about a day. The smell is not horrendous, it smells like latex paint.

The cushion itself is comfortable and provides support without losing stability. I waited ~2 hours before sleeping on it. I’m sure that the memory foam with expand to the listed size in time.

This pad worked well on a futon, which could use some extra help to improve comfort. Did not notice any problem with smell.

Mattress topper feels soft until you lay on it. Maybe it just needs a little time. But overall serves it's purpose.

I got this because my mattress i have now isn't very squishy and i am always questioning why i wake up with my back or something else hurting so i decided to give this mattress topper a try! When i say it has been one of the best purchases i have made i mean that. I no longer have back problems and i stay in one position throughout the whole night. I don’t think i ever slept better! If you struggle with the same problems I definitely suggest you give this a try!

We folded the full topper in half and zipped it up in a sleeping bag. It stays in my van for road trips... naps next to the ocean, and more. Love it!

Shipping was faster than expected, came neatly packed, vacuum sealed. Immediately started to fluff up after opening. King size bed is a 5 year old “purple” mattress and has lost its luster. This 3 inch memory foam topper from Marsail is a way better and cheaper option than buying a new mattress! Went from sleeping on what felt like a rock with body aches and pains in the mornings to literally the best nights sleep in a very long time. So comfortable and no body complaints whatsoever in the morning. I’m just mad I didn’t do this earlier, could have saved myself from pain and lack of sleep. But, honestly after looking into toppers, some prices were just a bit too high and not very thick. For under $100 and THREE inches of memory foam, this is a great value and worth every single penny. I am very happy with the Marsail Mattress topper and look forward to many, many nights of sleeping like a baby on my cloud like mattress.

I didn't really think about how thick 3 inches was until this mattress topper expanded on our bed. It really measures at 3 inches and is super soft. If you like a soft mattress, this will help. My wife likes a soft mattress. A few years ago we bought a purple mattress and it was just never soft enough for her so finally, I threw this on top and now she's getting some of the best sleep she's gotten in years.
