[This review was collected as part of a promotion.] My son (110 lbs) has been using this mattress for almost 3 weeks now. There is zero dipping or denting. My husband and I were so impressed with the firmness of the twin size mattress my son has been using that we purchased a king size for ourselves. We had just bought a standard mattress less than a year ago and with a few weeks we noticed dipping that did not bounce back. It amazes me that a memory foam mattress fared better than that. Our entire family is beyond pleased with the quality of Zinus memory foam mattresses.

[This review was collected as part of a promotion.] This is one of the best twin mattresses my family has ever had! My daughter and her twin brother absolutely love it. He sleeps in room just to lay on it. It’s super soft and has a cooling effect that is great for my warm bodied little sleepers! I actually go in her room during the day to lay on her bed when my back is hurting! It really is wonderful for pressure relief! I’d give this 10 stars if I could!

[This review was collected as part of a promotion.] Mattress is packed very well by the manufacturer. Got it inside and once opened (be cautious when removing from plastic not to damage mattress) it was at full thickness within a few hours. Unlike other memory foam mattresses this did not have a chemical smell of any kind which was quite a relief. I waited 24 hours to sleep on it just to make sure it was done expanding. The night's sleep was great. Woke up with no pain and slept undisturbed through the night. The mattress can be described as soft but firm. It will cradle you but you won't sink into it. Highly recommend for those who don't need an extremely soft or hard mattress. If you need comfort and support this one is for you!

I'm very happy with my purchase. I purchased two of the twin memory foam mattresses, for my children. They are quite happy with them, and say they are quite comfortable. They appear to be very good quality compared to my other queen size memory foam mattress; which was quite a bit more expensive, outside of the size difference. I would definitely recommend this product. I loved the convenience of having it delivered to me, instead of having to go to a store to pick it up.

Awesome. Same quality as one's that cost hundreds more. So comfortable! Using this as my primary mattress. Arrived in box about 4'x2' and about 60 lbs. Easily moved myself. Unpacking it was folded twice and compressed in airtight plastic. Once I removed the plastic, it expanded to full depth in about 15 min. From unboxing to full expansion was maybe 20 min. Sheets and mattress cover fit perfectly. Its one sided so you wont/cant flip it.

I got it for the top of my kids bunk bed. It was easy setup and also very comfortable my kids love it. It is the best price for the quality of the mattress most mattresses I have seen were about $200+ for a spring mattress that you can feel all the springs. I am ordering some more for my other beds.

We purchased 2 full and 1 queen to go with the Modern Studio Platform 1500H frames that we purchased. Each mattress comes in a box and is wrapped in plastic twice. We laid them out to let them fluff up and to my surprise, they didn't stink like some memory foam mattresses do. The price was good and they fit perfectly on top of the frame. Very happy so far!

I now have four of these foam mattresses from Sam's, in thickneses from 5" - 12" and all of them are better than anything I have ever had in the past...at any price. The fact is; sleeping on foam is the best rest you can get and these mattresses that Sam's sells are plenty good enough in any thickness.

This bed so far is excellent! I bought this to get into the whole memory foam craze with mattresses, and I only wish I got it sooner. They say this is a medium firm mattress but it's not too firm at all. You still get that contour feeling and it's just the right fitness. My wife and I love so far and it's only been a week.

Stinks after a week, put in zippered pad, ok now. Good quality materials, nice and thick. My son is happy with it and sleeping well. Got the XL for the added length (teenager). Came on time, very tightly rolled /vacuum sealed. Would buy again. I gave it a 4 because it doesn't seem to loose the stink. Tried to air out for a few days & had a fan blowing on it, but didn't help. When I put the mattress protector on, that stopped the smell. (very chemical smell)
