  • One of us loves it, one doesn’t
Size: 4 Inch Style: Twin Pattern Name: Mattress Topper
We bought the twin size for an extra bed in our house. It’s rarely used except when one or the other of us is snoring and the other can’t sleep 😂 My husband, 6ft, 185# thinks it’s great. I am 5’7” 140# and it’s too thick/too soft combination tacos me. I wake up with my shoulders in my ears, my arms rolled up on my stomach. If I’m on my side, my knees bent, then I’m laying crooked because my ass sinks, my knees don’t, my head and shoulders sink, my arms and hands don’t. I wake up with random muscles stretched too much in the wrong direction. So I do think your size matters as to if you’ll like this or not. The quality, timeliness, are all fine. ... show more

  • Very Good Mattress Topper
Size: 3 Inch Style: Twin Pattern Name: Mattress Topper
The only issue I have is I think my actual mattress is too soft so my topper sinks in a little. Other than that this topper is amazingly, out of this world comfortable. The first night I slept on it I slept the best I have in a very very long time. Usually my arms and hands go numb and tingle so bad that the pain wakes me up, but that doesnt happen with this mattress topper. I recommend this to anyone who has chronic pain. ... show more

  • Heavily sleep
Size: 4 Inch Style: Twin Pattern Name: Mattress Topper
This is wonderful. It has changed the game for me. I’m 6 months postpartum and my hips are all messed up from birthing my son. This has changed that for me. I would wake up with incredible back or hip pain and this has changed that for me. I don’t know why I thought I needed a whole new mattress. Would have been a waste hunting and buying over and over. This solved my problem. ... show more

  • GREAT Topper **Updated 8/24
Size: 4 Inch Style: Queen Pattern Name: Mattress Topper
***UPDATE 8/24 - I spoke with amazon and a replacement topper was sent to me since the original one I received did not match the picture being used in the product description. The replacement that arrived DOES match the pictures. I am surprised the pattern used makes such a big difference, but the pictured version with the circle pattern is noticeably more comfortable and stable than the version I originally received (which is pictured in my review.) It is still extremely soft, which is good, but you don't get "encased" AS MUCH as the version I originally received. I like the sinking-in, but this version is honestly better. It's still super soft and you still sink in, but with the circle pattern version (the version in the product description's pictures) I am able to lie on my stomach or side without bending my back significantly or rolling back down into the body divot if I switch which side of my body I am resting on. This is noticeably more comfortable than the $200 Serta cooling memory foam topper I used to have, and even more comfortable than the original (incorrect) topper I received from amazon. I couldn't be happier with it, seriously. ----------ORIGINAL REVIEW----------- Overall, this is an excellent product, especially for the money. Some people are complaining about it being too soft, to which I would reply that it's a 4-inch memory foam topper and that should be expected. If you want something more firm, get a 1 or 2-inch version. For me, I wanted it really soft, and I sink into this topper very well. It expanded within 12 hours and there was not really any smell to it as others have also complained. The issue is that it is not as pictured. The patterns are all different, and I was looking forward to the version in the pictures. I have attached a picture of the version I got. I reached out to the company and they said that the item was shipped and sold by amazon so I would need to contact amazon about a replacement. ... show more

  • Mattress topper adds needed comfort
Size: 4 Inch Style: Twin Pattern Name: Mattress Topper
My wife sometimes sleeps on a twin bed to escape my snoring, but the twin's hard mattress made it difficult to find comfort. This mattress topper fit the bill perfectly, providing just the right amount of cushioning to offset the mattress's extreme firmness. Most people should find it very useful on hard or slightly saggy mattresses and a practical alternative to buying an expensive new mattress. ... show more
