Sleeping in this bed felt like lying in quick sand. When you first sit or lie on it you think it feels firm but plush but then you continue to sink in further and further to where it's hard to move from one position to another. I hated this bed, I literally felt claustrophobic trying to move around in on this mattress.

This indicates is medium firm but is by far the softest mattress I've ever had. I need a much firmer one. It also had lumps from not evenly expanding. I need to return it. Unfortunately, since I picked up in store instead of ordering online, I need to return it to the store. (The store was extremely rude when I asked about options.) One gal on phone told me to 'just roll it back up'... guessing she doesn't understand how these work :)

Bought this for my 2 years old. Toddlers need medium firm for their spine development. I waited 3 days to fully expand but It was still soft. It is softer than soft mattress. I am 240 lbs and when I sit side of the mattress I drowned all the way down to box spring. It is still okay for my 2 years old because she is only 35 lb but If we want to sit on it for putting her to sleep It is really annoying. So I returned and got the one with springs. My 3 stars goes to Sam's club customer service.

I purchased this mattress quickly online without spending much time reading its description. Just a lot of satisfied comments and an attractive price. If I had known it was a "bed in a box" I probably would have passed it over in favor of a traditional mattress. When it arrived, I was surprised and nearly returned it without opening the box, but after rereading a lot of happy online comments, I decided to give it a try. This is the most comfortable mattress I have ever owned and I look forward to many happy years with it.

Gave this product a 3 star for poor operational service, not quality of mattress. Received a banged up set of brown boxes that were taped together and thought that this must be the shipping box over the official Members Mark Box I saw in the store on a mattress of a different size. Unfortunately No. Opened up the brown mishmash of boxes to find a shrink wrapped mattress that had OBVIOUSLY been previously opened, that someone must of returned, that was rewrapped and shipped out, instead of a NEW mattress that I ordered and paid for. I decided to forge ahead and bite the bullet since I needed the mattress and it appeared that it was unused and clean. Took 6 days to fully expand and firm up Mattress has so far lived up to expectation Shipped and arrived ahead of schedule

I give 1 star because I’m sure other people like it that soft but I expected it to be a little firmer for medium firm, but it was so soft you sank so far in it hurt my back when laying on my stomach. The smell was just plain god awful and didn’t go away even after airing it out for over 48 hours with windows open in the room. The smell gave me migraines as well as made my sinuses hurt. We returned the bed and ordered one of from Walmart that has been much better.

This is my first mail order mattress, so I was a bit skeptical.Mattress arrived quickly and I was able to get it set up by myself. It immediately took shape once plastic was removed. After just a few hours it was ready to sleep on. It is a quiet mattress and I would consider it plush to firm. It almost feels like the mattress absorbs you, very little bounce when moving on it. The sides are not firm when you sit on them, but that has no effect on the sleep quality I've gotten and that's not an issue for me at all. If you must have super firm and supportive bed edges, it may be an issue. I have less back and neck pain since sleeping on this mattress and wish I'd bought one sooner. I feel like it is a good value for the price and I very pleased with it. I hope it holds up well.

I hesitated in buying a new mattress for several months. There are SO many options out there, all of them claiming to be the best. I spent lots of time researching prices and pros/cons for several brands. Friends of mine told me I would never get a decent mattress for under $1,000. Well, I am here to say they were wrong! I am so happy with my decision to go with this one. This is definitely the most comfortable mattress I have ever owned. When I first laid down on it, it seemed too soft, but that was because I didn’t give it the full 24 hours to fluff up. Now It’s firm, but not too firm. Soft, but not too soft. It’s just perfect for me with a history of back issues. I’ve been sleeping so well since I got it. Thanks for making an affordable option that is still so amazing! I would 10/10 recommend.

This is not really a firm mattress. Some areas of the mattress are softer than others. Our backs have hurt every morning since the purchase of this mattress. I would love to return it but there is no way for me to transport a king mattress back to Sam's Club. It was delivered vacuum sealed in small box and then expands to full size.

Mattress did have a chemical smell for a few days. It does sink at the edges when you get on and off the bed. It did take half-a-day to firm up. AND this mattress is the perfect balance of sinking into the mattress but not sinking too far. It's one of those mattresses that will not hurt your hip or shoulder if you stay in one position for hours. But you do not feel like you are on a hammock:) You feel like you are on a well made, expensive mattress that was a bargain!
