This mattress is aweful! The 12" must have been measured by a man, because it's only 10". There is NO support, and my wife and I both woke up with terrible back pain. I've slept on cots that were more comfortable.

Very comfortable. Im sleeping so mich better than i used to. Our old bed was sinking down about the time we bought this (right before we bought this one). Once it expanded we havent had any problems. Even comfortable after surgery.

I like the semi firm mattress. With that said, I would like to report 2 issues: 1. I ordered online, item came without original box, which is having wheels for easy movement. 2. Top part of the mattress is getting wavy after every use.

I’ve bought mattresses with Sam’s before but never the member’s mark brand. Exceeded my expectations and will buy the same style in the future for guest rooms.

After 30 years of expensive mattresses, I decided to give this a try. I usually use a firm mattress with an additional foam topper so I purchased the medium and it’s perfect. Snuggly on top with good support underneath. Great value.

Love this bed! We had a sleep number for 20+ years and needed a firm mattress, this is just as good and a great price! Plus you just open up the box and the bed is ready in a few hours!

I have been sleeping on my new mattress for about a week now and so far so good. I bought the firm and in my opinion it's a semi firm, not a luxurt plush though. It works for me.

The mattress is cooler than my last one. I immediately slept better from day one. Also bought online cheaper than the store. Free shipping. Will buy again without hesitation.

It says medium but it felt like a rock to me. Thankfully they accept a return. Note for COVID mattress returns all you need to do it cut the mattress tags off and return. Then discard mattress on your own.

Sleeps great. Easy to carry and expanded quick. Tried on a platform, but it slid around too much. Using it on boxsprings. It's one of the most comfortable mattresses I've also on.
