    • QUALITY AT ITS BEST PRICE
Size: Twin Style: 2 Inch
I am very happy about this mattress that I ordered a second one right after I received the first one. The design of the mattress is so attractive that you want to lay on it and sleep. It took only a few minutes before the mattress expanded to its normal size. The thickness and firmness are just right for our hospital bed making it so comfortable to sleep on. The second one we used for our small sofa bed. Thank you so much! AND....most especially, this is Quality at the BEST price!!!! ... show more

Game changer for my IKEA daybed. The best mattress I could find for my trundle day bed was hard as a rock. I put this on top and it's sooo comfortable.

    • Just meh
Size: Twin Style: 2 Inch
I've had this mattress pad for about 5 weeks and so far I'm not impressed with it whatsoever. The best adjective I can think of to describe it is "frustrating". It started with taking longer than expected to expand, to now the thing just doesn't stay in place. It comes wrapped in plastic with all the air removed, making it very flat. You need to leave it out in the open for a few days so it will expand to it's full size. I've had other memory foam mattress pads, so I knew it would need a day or 2 to expand, no big deal. At first, all seemed well, the pad was expanding as expected, but after 24 hours, I noticed about 8-10 inches along the whole length of each short end that were just flat and misshapen. After 48 hours they were still flat and misshapen. I tried gently scrunching and rubbing the flat ends and the next day they were less flat but not quite fully expanded, so I did some more scrunching and rubbing and by the 4th day the pad was finally looking normal. I put the mattress pad under my mattress protector when making my bed, and all seemed well at first. It's now a month later and the mattress pad doesn't stay in place. It moves, or rather slides itself out from under the mattress protector. I wake up each morning and the mattress pad has slid about 6 inches off the side of the bed. Why?? And the only way to fix it is to strip the sheets and mattress protector off the bed, put the pad back in place and remake the bed. Like who has time to do that everyday!? And to top it off, I don't feel like it's adding much of a cushioning layer to my bed. So basically like I said above, this thing is just frustrating and I don't recommend. ... show more

I saw the box and thought what did I buy? It's was scrunch and little. After I placed it on the couch it started to expand into a beautiful blue memory form butterfly 🦋. This thing is softer than melted butter. I purchased it for the couch for guest. It stores perfectly rolled behind thw couch unseen until ready to use. We'll worth the purchase and the quality is excellent. ... show more
