Sadly this is so lumpy and even allowing an extra week hoping that it would expand more did not work to fix this. I had to return and exchange for a mattress that did not come in a box. The idea is a good one if they can prevent the top of the mattress from the bunching up.

We purchased this mattress for our guest room. My in laws stayed with us and like the mattress so much they bought one for themselves when they got home. They said they didn't have any pains the week they were with us and noticed a difference immediately when they got home.

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 isn't the medium-firm mattress that I was hoping for, but it still is a decent mattress. I'd consider it firm with a slight (very slight) "give". The give isn't enough to drop it down anywhere into the medium range, but it's enough to provide decent support to back sleepers. I wouldn't recommend for side sleeper--unless that person is thin with narrow frame/shoulders and/or loves a firm mattress. Even heavier family members don't get much sink. Sometimes mattresses like this will bottom-out. This one is just firm. The sides do not have too much support so if you're a sleeper who prefers a big more sinking feeling you may find yourself sleeping on the edges. Just be careful that you don't roll onto the floor! We didn't notice any off-gassing (which is both good because it's ready-to-go but also bad because it's rather suspect given the materials). Overall, this is a gem of a mattress given the price if you're seeking a firm memory foam. I'd probably consider more for a guest room or child's room. I purchased it for a main bedroom mattress but it got moved to the spare room which we use when we just want to stretch out or take a quick nap. This mattress has more of a "sleep on top" rather than cradle/sink-in feel so it just depends on your preference. I haven't had it long enough to see if it gets much softer over time. A steal for the price. But still not right for my nightly comfort preference. (I wonder if quality control is an issue if people are actually getting/experiencing a softer sleeping experience). Overall, an okay mattress. Great for the price.

You will be hard pressed to find a better value for a mattress in this price point. We bought this as a guest room mattress, but ended up needing to use it ourselves for a few weeks and were very happy with the comfort and support it provided. It's not too firm, nor too soft - a solid medium support mattress. Highly recommend whether you're looking for your every day mattress or a place for guests to lay their heads.

The mattress was not comfortable. It felt like sleeping on a bunch of pillows stuffed inside a casing. Lumpy and no support. I love Sam's but had to return this. The only requirement for the return to store was to wrap in plastic. Easy return no questions or hassle.

Totally as advertised. It is a firm mattress. Motion transfer is minimal on a platform bed. We did end up using a plush mattress cover to soften the top just a little. Very happy with the purchase and the price. Delivery was quick. Follow directions on opening as it recovers shrink wrapped very quickly. We let it expand about 7 hours. Slept great the first night and every night since!

I redecorated my son's room and was originally looking for a mattress topper to bring life into a VERY OLD mattress. A quality topper is pricey and I figured it would be a temporary fix which would ultimately lead to a new mattress sooner than later. I stumbled upon this Member's Mark mattress at my local Sam's club during my topper hunt. The price was double the price of a nice topper, so I decided to skip the topper and go straight for a new mattress. After a couple of days of expanding, it is really nice. My son only comes home from college occasionally, so it is a perfect addition to his room. Personally, I like a firm mattress, but when I lay on this one to test it out, I'm pleasantly surprised at how comfy it is. My son loves the way it sleeps and never complains any more about coming home and staying for a while.

Mattress is very comfortable - softer top with firm support. A high quality mattress that doesn't break the bank. It was easy transport since it comes in a box. Be sure to have the box spring/platform bed ready for the mattress because once you unravel and cut open the plastic it is heavy and harder to move around then when in a box :)

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.
