Received the mattress, let it expand, and it completely dips! We sink in towards the center when we lay on it. We took a nap on it, and my back hurts from trying not to roll towards the middle- similar to an air mattress. I didn’t know memory foam could even do that?! How in the world would I even send it back?! We’ve had several memory foam mattresses and never had this happen. It’s fine otherwise. Can I get a replacement? Not even sure how that works!

I can't speak to the long-term reliability of this mattress yet because we've only had them about a week. But i bought 3 of the twins for my kids 2 sets of bunk beds with trundles. I had 3 innerspring mattresses and needed 3 more and this is what I could afford and I had worried the kids would fight over the traditional thick mattresses and not want to sleep on the thin "cheapies". However , the opposite is true.. all 6 kids from 7 to 17 wanted the memory foam mattresses and say they're extremely comfortable and soft. Looks like I'll have to buy 3 more. My only complaints are that they're a little flat on the corners and they're more like 7.5" instead of 8" but for the price they're great beds and the kids love them.

I read most of the reviews and yet decided to trust the positive reviews and order this mattress. I unpacked and let the mattress expand for 48 hours and the actual height of the mattress is barely 5 inches. Its very uneven with 4.5 inch in some places and 5.5 inches in the edges. My boyfriend ordered from a different brand and it had raised within 12 hours and to its full height within 24 hrs. I patiently waited thinking it would reach 8 inches but no. The matress doesn't feel like memory foam at all, its too firm to be memory foam. May be my piece was defective but I don't know there were many others who had similar experience like mine. So, no more Zinus memory foam for me.

This Zinus Night Therapy Memory Foam mattress is like sleeping on clouds. Very comfortable. I bought this for my 18 year old son and he said "mom this mattress is AMAZING". He is very happy with it. Now its even harder to get him out of bed. I'm very glad I purchased this mattress.

By far Best Deal For The Money!!! I got this twin size mattress for my son. I have not slept in the bed but I have asked him and he tells me that it is very comfortable. What I liked the most was the price! If it was any higher I would have gotten with a different mattress. Thanks.

I have never had a memory foam mattress before. Initially upon sitting on it, I didn't like it. I went from a medium firm expensive mattress that was about 12" to this one. It is 4" shorter so I am lower down (I'm short anyway) and the other was a traditional type mattress. I have to say, after trying it for a few night, so far I like it.

I have slept on a few foam mattresses before and this one is by far the BEST! I bought the queen and it fits nicely on my frame. It might be an inch or two larger than a queen, but it still functions perfectly. The only issue that I had was with the shipping. I was told it would ship on a certain day an then I was given a delivery date. Halfway though waiting for it I find that it just shipped that day and it took about a week longer for me to get it. It came packaged nicely and it was easy to set up: You just pull it out the box, carefully cut open the plastic and let it roll out. There was a slight smell, but that went away within a few days.

This mattress said that it had 3 layers and until yesterday October 12 2022 I have come to realize that it only has 2 layers because I open the outer lining and saw that it only had 2 layers, and the high density layer is not high density, because it is to easy to smear. For that reason I have never felt comfortable on this mattres, I thought it was the base of the bed. Money wasted.

I really like this Zinus memory foam mattress! Very comfortable! Firm yet it relieves the pressure points, from my legs and hips! I had a Zinus memory foam mattress that was over twenty years old, and in the last six months i started noticing it was time for a new mattress. I only gave it a four star review as here's hoping the new mattress lasts as long as the other Zinus i had! LOVE IT!

I bought this mattress based on the fantastic reviews but I guess unlucky for me I got the faulty one or incorrect item. Really disappointed as it never rose to 8" plus it's extremely soft. I requested a replacement which took a while to arrive, got it yesterday, hoping this one is 8" thick and not so soft, giving it time to decompress.
