Got the King size. Fit the bed nicely. Not too mushy and not too firm. Mine didn't have any smell to it, so that was great. I liked that it has the cover. After unpacking it, it puffed up quite quickly and looked good right out of the wrapping. I recommend the 4". I'm 205 lbs, so it allows me to move around in the bed without discomfort. I already have a good mattress, but really wanted a mattress topper. This was a good buy for me. Made the mattress a lot more plush without being too flat. Gonna buy another one for my daughter.

Left spread out for 48 hrs and not quite 3”. Definitely adds to comfort but prefer regular foam mattress toppers I bought at Costco for half the price!

This mattress topper provides just the right amount of comfort and support.

Been using the 4" new version for about two weeks now. I absolutely love it! It's revolutionized my sleep AND my wake up. No more back pain, and much better quality sleep, i.e. deeper and for much longer periods. I listened to Lindsey and you should, too. She is 100% right about this thing! I was lucky to find this terrific topper on sale, but even at regular price, I would say it's a bargain for all of the benefits it provides. The seller was great, too. Fast shipping, nicely packaged, exactly as described. Mine puffed up to full size in just a few hours. The cover and straps are nicely done and very helpful. All in all, a classy item and a classy experience, just the way I like it. This topper is literally the gift that keeps on giving...every night! :)

This is a very good topper I put it on my mattress that already has a pillow top.and mow it's too high. Im not returning it because it is my fault it didn't work so I am giving it to my daughter.

Product is comfortable, not as hot as some. Definitely not 4" thick it is 3". It has been 10 days and is definitely done expanding. There was a slight odor when first opened but definitely dissipated quickly, no smell now.

Thought I'd give this a go. I'm getting old, my mattress is getting old and wanted a bit of cushion to give the hips a little relief. So far, so good.

This foam mattress topper is very soft, and makes my sleep very comfortable. I would highly recommend this to anyone who has neck, hip, shoulder, back issues.
