After much research we chose this firm, king size mattress. After originally leaning towards a hybrid mattress with springs and foam, we are extremely pleased with our all foam mattress. IMO, the addition of springs just adds an unnecessary quality risk with the way these "bed in a box" mattresses are packed. We had concerns about returnability and felt that a Sam's Club product (Members Mark) would be more highly supported in case there were issues. This mattress gives firm support, yet is comfortable whether a side sleeper or back/stomach sleeper. Without a legitimate firm mattress we are subject to back discomfort. After 7 nights of use we are happy to say that we are extremely pleased with our choice.

astronomical mattresses. Definitely choose this one over the new hybrid one. My entire household has these in all sizes. I bought my first one about 5 years ago and it hasn't had any impressions or imperfections. highly recommended. It has significantly reduced my lower back and hip pains. even the dogs love it

Better than expected. I did NOT like memory form mattress because I prefer firmer mattress with steadily support. I hate the endless sinking feeling that my husband's old memory form had as well as others I have tried. But this memory form mattress from Sam's does not give me that sinking, unstable, wobble feeling when in bed. I choose firm and to me it's medium. But good enough. I think firm is ideal for face-up sleepers but less ideal for side sleepers. The remaining question is how long can it stay in shape without becoming too soft or even collapsing.

I love this mattress. We purchased it in Feb 2021 and I feel like I’ve given it plenty of time to have any issues and there are literally non that I can think of. I want 3 more of these. It is literally my favorite mattress in our house. Cannot recommend enough!

Sleeps comfortably.

Not as firm as I would like it. If you are looking for a bed that is stiff as a board, this isn’t the bed for you. It’s not bad, but not quite what I was looking for. It’s plushy with a firm feel. Overall, it’s not a bad mattress. I would have liked it to be firmer.

I tried this mattress during a recent trip to the Caribbean and had a great sleep experience. I took a picture of the mattress, knowing I'd need a new one soon. A few months after my trip, I decided to purchase it. 1. Delivery: Arrived on time, even a day earlier than expected. 2. Condition: The mattress was well-sealed and arrived in good condition with no visible damage. As a 5'2", 140-pound 39 yrs old woman, I didn’t found it challenging to unpack alone. 3. Comfort: The mattress is very comfortable. I fell in love with it instantly and hope it remains so in the long term. The following factors led to a lower rating: 4. Odor: The mattress has a strong paint-like smell. During my trip, I experienced a running nose and shortness of breath upon entering my accommodation, which I initially attributed to the weather. However, upon unboxing the mattress, I experienced similar symptoms again, which makes me wonder if it's related to the mattress odor. 5. Durability: As I've just received the mattress, I cannot yet assess its durability. I hope this review provides helpful insights into my experience with this mattress.

Love it! Great quality!

The reviews about it being too soft are correct. I have another memory foam mattress. Different brand. That is plush and isn't nearly as soft as this medium. It feels like you went to sleep on an air mattress and woke up in the middle of the night and it was flat. This is excessive. I like plush. But this is next level. It almost has me wondering if they put the wrong one in the box

So my partner and I originally purchased this one mattress in 2020. At the time, it was the most incredible mattress with great support- we couldn’t believe it was only $400. After owning it for two years we noticed the mattress wears down a lot quicker than what a mattress should and wanted to exchange it thinking it just may be a minor defect. Sam’s club was kind enough to exchange it for us behind their member mark lifetime warranty guarantee. When we got the new mattress we immediately could tell that it didn’t feel the same as the original one we purchased. We have it it a chance thinking it just needed a few days out of the box but unfortunately it just wasn’t the case.
