This mattress is firm. I read all of the reviews but took my chances. We added a 3 inch memory foam which helped a lot. Its for my 5 year old son but ol mom lays down with him when he wakes up in the middle of the night. So its taken some getting used to, but overall I am pleased. Easy to remove from box and we waited 34 hours before using it. It clearly states when you receive the mattress that you are welcome to still sleep on it even though it may not have fully expanded yet, but we chose to wait.

I thought it would be more hard than it is, usually I rollover at night and it feels like I am in a hole , the middle of the mattress is not as hard as side, probably will be returning to get a harder one . They make good mattresses, but this is too soft for me.

We ordered a couple weeks a go, I’m glad I choose this mattress, but one thing I give this 4 Stars because when we open up the mattress is was a stain on it, like lightly brown stain. It not like a very noticeable so I keep it. I don’t mind, the mattress satisfy me a lot!

I purchased a foam mattress years ago and needed another one. So I went on line at Sam’s club.com and purchased this one. It arrived just as promised. After taking it out of the box as instructed and placing it on the bed to allow the mattress to fully form its correct shape, what an amazing comforting product!! Even days after it had continued to form and firm!! Extremely comfortable but firm!!!

Very disappointed that it never rose to 10" level-- stopped at 8.25". Only reason for a couple of stars is because Sam's Club accepted the return with no problem. The mattress construction looked same as the one I have, which inflated instantly to the full thickness upon opening the box, but Zinus mattress never reached the height after 5 days and nights. Should have listened to the other reviewers with the same issue.

I am disappointed in this product. It was supposed to be 10" mattress but after a couple weeks it still is at 9". The top layer of Memory Foam is too soft. Never seen memory foam to sink this far. Would not recommend. If I could send back I would be since it's so big I can't.

Jeepers this mattress even helped my hyper dog get some deep sleep with soft snoring!! She didn't even get up when I made a restroom visit. I'd say the pressure, weight and pain I've felt between my shoulder blades for over 20 years has lessoned by about 70%!! It could be that what is left is residual from my back bothering me for so many years. I wish I had bought this years ago if it was available and what an excellent price!!

Love these mattresses! I have purchased this brand and style of mattress for every bed in my home. I just finished purchasing for every bed in my second home! Don’t waste thousands on fancy mattresses. This bed is super comfortable and durable. And it comes to your home in a box!

I have had this mattress for about 2 weeks now. I gave it a full 48 hours to decompress but it took a few days to get to the full 10 inches but eventually it did, no funky smell to it for me. It’s a little firm for me but I added a mattress topper and now I’m sleeping like a baby! Overall great quality for the price paid. I’d recommend it.

We bought 5 of these for a vacation rental, one 12 inch and four 10 inch. We’d have bought five 12 inch but only one was in stock. Timeliness and convenience of delivery and set up were great. We slept on a 10 inch for a couple of weeks while there working on the property and found it very comfortable. The quality of materials and construction look good. I expect we will get a number of years of good service from these mattresses. We do love our $4,000 Intellibed mattress at home but these inexpensive mattresses from Sams Club offer a very similar nights rest.
