[This review was collected as part of a promotion.] This mattress is pretty hefty. It weighs about 90 pounds. It took two people to end over end it up the stairs. Once you get it out of the box don't unroll it from the outer plastic until you have it in place where you want it to go. Once I had it on top of my queen box springs which was on top of a platform i started to unroll the outer plastic. I could here it already hissing a little, so that meant it was starting to expand. It stated on the handbook that it would take 24 to 48 hours to fully inflate. It had fully inflated less than 24 hours to me. I would use a box springs or platform not both. I am using both and it is so high. Since the mattress is 12 inches, the box spring is almost that and the platform is about 1 and a half to 2 feet of the ground. The puts the mattress at my stomach and i'm 5'4. The Member's mark Hotel premier collection mattress is really comfortable. It forms to my body in about 5 mins of laying on it. If i turn over it re forms to my body. I really enjoy the cooling effects on my body from the mattress. I am a hot natured person and this bed kept me cool all night. It feels like you are sleeping on clouds. I would love to try this out in a king size bed as well. I really slept well on this mattress.

I've slept on it for 2 nights and taken one epic nap on our new matresses, and i LOVE them! Our 12 year old Icomfort mattress had given up. We had decided to get 2 twin xl's in hopes of getting an adjustable base in the future and the 2 twin xl's were actually $50 cheaper than just buying a full king size. I can move these 2 all by myself where our old matress was so heavy it really needed 4 people to move if you were to follow OSHA saftey standards due to the weight ;) We got the medium, i let them "air up" for a little over 24 hours and they had no issues or a bad smell. I was a bit nervous when they were delivered because one looked like it was trying to air up in the box, so i was scared of it being mishappened or damaged from a cut through the box or something, but had no problems. Not to firm not to soft. Being 2 twin xl, there is very little if any movement transfer. King size bedding fits on the 2 mattresses perfectly and keeps them together better than i thought it would. Being 2 mattresses together, they are a smidgen wider than our current bed frame, so if you have a frame that the matress sit in that may be a issue if you go the 2 twin xl to make a king route. I paid $327 total after taxes for both and they arrived in 2 days! I bought from Sam's so if we didn't like them we could take them back to the store if there was a issue, as this was the first time buying a mattress that i didn't get to test out first and i was nervous, lol. I figure even if these break down after a few years, i would still be happy with my purchase because I've wasted more money on way less before. For the price, they are totally worth it and with the return policy, no reason to not try them out. We got the medium, which is fine for us, but if you like a firmer matress get the firm one. I'm ordering one for our 16 year old son, who has never had an opinion on bed comfort because he could sleep on the floor and find it comfortable. But he laid on it and said he wanted one too! The price is great! Trust me we went mattress shopping and i think we laid on every major brand mattress on the market these days and I'm telling you, there are way worse (name brand) matresses for quadruple the price out there

[This review was collected as part of a promotion.] I initially got the mattress for my guest room but after I unpacked it and tried it out, I decided to move it to my room! The box is amazingly small, but the mattress was easy to open and then like magic, it ‘blooms’. It’s hard to believe that a regular sized mattress came out of that box! The cover on the mattress is very soft but feels durable, and the cool touch is wonderful for Texas! This mattress feels soft and luxurious and supportive all at the same time.

[This review was collected as part of a promotion.] I received this product a few weeks ago and I am so happy I did! This product is extremely comfortable! If you need the best sleep ever then this is the mattress for you!! This mattress is definitely very well made. There is nothing about this mattress that I dislike.

[This review was collected as part of a promotion.] Its unboxes like any of the others. Carefully cut plastic and unroll bed. Then cut second set if plastic and watch the magic that is a 1" bed grow into a 12" mattress. Remember those grow a dinosaur by adding water pills as a kid? It's kinda like that without adding water. I did not experience an odor with any of these in the slightest, even when first opening. Okay so this is the best bed I have ever slept on. Slightly firm but I like that. This mattress is great quality and inflated fully within 30 minutes. It moved around tight corners nicely also.

[This review was collected as part of a promotion.] This mattress was supposed to be used in our guest room but it was so comfortable that we switched out or master bedroom mattress with it. It was delivered in a box to our front door which was amazing. It quickly rolled out and took its shape. I was pretty amazed. It keeps me cool which is a huge bonus!

[This review was collected as part of a promotion.] I absolutely love this mattress by members mark. First off the 12in part is awesome. I love how the mattress forms with your body. It's so soft feels like I'm on clouds. No more shifting also from your significant other. You cant even tell if there a wigley sleeper. My sleep has improved so much. I also love the cooling sheet it has on it,feels so nice. This is a must have mattress.

[This review was collected as part of a promotion.] We are very happy with this new mattress. It was easy and almost fun to open and "install". It is also incredibly comfortable. They are not kidding when they say it is hotel quality. This mattress is pillowy soft and we look forward to many years of using it.

[This review was collected as part of a promotion.] This is a firm mattress to me. It sleeps good and is comfortable. The mattress comes rolled up make sure you put it where you want it and roll it out. Mattress starts rising immediately. The mattress is made with a soft cover and is memory foam.

[This review was collected as part of a promotion.] This is the best and most comfortable Hotel Premier Collection Member's Mark 12-Inch Mattress that I have ever had. I have been working from home for the last three weeks so the Hotel Premier Collection Member's Mark 12-Inch Mattress has been my office. I can say that it’s an office I never would like to leave that’s how great it feels. I know that this has been the best sleep that I have had in years no waking up at night or tossing and turning just peaceful sleep. I liked that it was easy for me to move around on my own. You have to wait a few days for the Hotel Premier Collection Member's Mark 12-Inch Mattress to fully expand. I am so in love with this Hotel Premier Collection Member's Mark 12-Inch Mattress I would recommend it to all of my family and friends.
