This is the fourth zinus 13" I've purchased. The first was two years ago, it's our primary bed, and it's still wonderfully comfortable. Another for my daughter and two for an airbnb house we have. The springs are supportive yet the top is soft. .They say you should replace your mattress every few years (a marketing strategy I'm sure) which has prompted me to stop investing heavily in them. Why get a mattress w a 10 year warranty if I'm supposed to replace it every 8 years?

This mattress is magnificent. From day 1I sleep all night without pain. The only reason I gave it a 4 instead of a 5 is because it has a little bit of a strange odor it's taken about a week and a 1/2 for it to die down great purchase would definitely recommend.

Bought it about a month ago. I was hesitant at first because we never bought one in a box let alone a mattress at this low of a price. If it wasn't for the other reviews I probably never would have. However, so far so Great!!. It arrived a few days earlier than projected in the box. We followed instructions and let it relax for 48 hours. Really have no negatives. Now we have to see how long it will last. Very, very satisfied as of now.

This is the fourth Night Therapy mattress that I have purchased and have been pleased with all of them. They all arrived in a box on the doorstep and all I had to do was open it up and remove the mattress from the plastic bag. The mattress immediately started expanding and within 24-48 hours (recommended time), you have a nice mattress. I purchased three of these mattresses over the past year for my adult childrens' guest rooms so I would have a comfortable place to sleep when I visit. The fourth was purchased for my guest room. I wouldn't hesitate to purchase this mattress again. For two of the mattresses, I purchased the metal bed frame from Samsclub and one was placed on a platform bed. It is the perfect height. My adult son liked the one so much that I purchased for his guest room that he purchased a king mattress for his master bedroom. They have been happy with it.

Mattress is firm. I was worried about the odor as so many other reviewers commented on it but mine had no smell. Great value although it never did expand to 13”. It only got to 10 1/2. I had to get a low profile box spring since it was less than expected.

I bought this mattress a couple of months ago. It took a few weeks for me to get used to it and for the mattress to "soften up," but I love it now. I no longer have lower back pain when I wake up in the mornings. It sleeps very well. Not too hard; not too soft.

Never fully inflated, you cannot sit on the edge of the bed without having to really hold yourself up with your feet. When you sleep, because the outside edges never fully inflated, you roll to the edge of the bed unless you're sleeping directly in the middle. 0/10 do not recommend. This is the 3rd time this mattress has been replaced because of some defect. I've had this particular mattress for a few weeks, so it should be inflated by now. Box springs are awesome, though.

Upon receiving and opening this mattress that it would expand at the corners to its original size after the condensed packaging but after a few days it did. It is firm which is my preference and is amazing comfortable. It is a great value and I highly recommend it!

We purchased this for our son and have had it about a month now. The quality was apparent and frankly more than comparable to higher priced better know brands. It is firm and provides excellent support. My son loves it and sleeps comfortably on it. It is truly an excellent value. Way to go Sam's Club!

It's thicker than I expected, the firmness is perfect, and I seem to sweat a lot less at night. I would buy this again and absolutely recommend it to others. The box it shipped in was way smaller than expected. This mattress is very heavy, make sure you have it right side up when you open the vacuum seal because flipping it is exhausting.
