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

Do not buy this bed If you are on the heavier side i weigh 280 my job provides a twin size mattress and i sink in completely there is no support and because it compresses so much there is no air flow so it becomes hot and uncomfortable this may be a good bed for thinner people i dont recommend if you are on the plus side

I was very disappointed. This bed was warm and worse way too soft. It was so soft the sheets were constantly popping off. After calling Members Mark and trying it for almost two months this bed had to go back to the store. Check out the new Casper line… Im MUCH happier.

Very comfortable

The bed came well packaged and very securely wrapped. As soon as I opened the packaging it completely sprung into shape with no issue. We're waiting a full 24 hours before laying on it. We ordered the medium and it's plenty soft and plush. I think it's perfect for my daughter but for me personally I would use the firm.

This mattress claims to be medium/firm. 100% not the case. I should have read the reviews because it is way too soft. To make a long story short, this is the worst mattress I have ever bought. Please don’t make the same mistake I did and purchase this bag of feathers.

When we were looking at the matress selection at Sam's we couldn't find Soft type mattresses in store that would work with adjustable bed frame. We ended up on going with this medium firm Members Mark Hotel series and it turned out to be exactly what we wanted being that it's in a box and you can't try it out in store it actually was softer then what we pictured and for a side sleeper you feel nestled into the matress rather than on top and using pillows to get support its so nice what a difference it makes to sleep better.

Do not buy if you have any form of back issues. I let fully expand before sleeping on it, I would wake through the night with lower back pain which isnt uncommon and reason why i bought bew mattress so i didnt think anything of it. By morning the pain is completely unbareable ive never experienced pain this bad. There is zero support with this mattress and is on the plush side nothing medium about it.

This mattress is a year old. I paid $399 for it. It has already broken down on one side under the weight of a 165 lb man who does not move a lot during sleep due to disability. I have mattresses on adjustable beds that are older and have not yet broken down under my weight or the constant up and down of adjustment. I'm not very happy.

I have on one of these Eight months now .. Always had the 3000.00 Temprapeutic Mattress.. My temprapeutics usually lasts About four years, i'm a big guy I've owned 2. I have enjoyed this sams version as much as the expensive version.. I've seen people complain about the Smell , That's something you have to get use to with any memory foam mattress.. My only dislike, It has about a half inch topper that wrinkles up and there's nothing you can do about it . (temprapeutics have zippers) This is reason it's not getting the full five ... price value ,five stars.. Comfort level ,five stars..
