We purchased a full-size, firm mattress for our spare room in February. It's now June. I waited to leave a review, so I had plenty of time to try it out. It is definitely not firm. I sleep on it 5 nights a week. It's soft, and your body sinks. It might be firm for a child, but anyone over 100 pounds would not say it's firm. Would not recommend or buy again. .

I was a little bit on the skeptical side that this was going to be a 12 inch mattress when it came in. But after we got it out of the box and set up it lives up to its brand and description 100%. This was a new bed for our son's room (twin ultra plush) and he loves it. Sleeps so much better than he did on the old spring mattress. I would definitely recommend this mattress, it is very comfortable and easy to set up once it's out of the box it will take shape in 5 to 10 minutes. I love how easy it was to handle compared to a box mattress, like night and day. I do suggest getting a mattress cover or pad for it if you are buying for younger children since it is foam on top and will soak up everything.

After getting an adjustable frame decided time to change mattress. Biggest problem was getting the old one off and ready for disposal and getting the plastic off the mattress was bit of challenge being careful not to cut the mattress. Once in place it began to hiss and start to expand quickly. Was surprised it only took a few hours to expand to 11 of its 12 inches! Very comfortable. Have seen reviews saying too soft but they must like sleeping on a rock as this is advertised as medium firm and would say that is right. So far so good and if run into problems in the future will come back to amend. So far very pleased.

The musty chemical smell is has been just absolutely horrible. I have been sleeping on this mattress a month and it still smells. I'm have been waking up with headaches since day one from the smell. Plus with the poor support you sink down in it to far. I don't recommend this Hotel 12" Premier Queen mattress and I would love to return it!

King mattress purchased via pickup at local Sam's Club. First the box weight is about 80 pounds. The Sam's associate brought it out on a flat cart and didn't even attempt to load it in my truck. Never offered to help even as I stuggled to lift in the back of my truck. Got the mattress home and removed from box. Removed the plastic. I let it expand for 72 hours. It seem the cover is bigger than foam. When we put it on the bed the cover bunched up and was very loose.

This is the second foam style mattress that we have purchased. We have the King Serta 12" Sleep-To-Go mattress in our master bedroom, which we really like and have had for over two years (also purchased at Sam's). We wanted to save money on a mattress (queen) for a spare bedroom, so we went with the Members Mark brand this time. It was pulled out of the package yesterday early afternoon, but after about 8 hours of expanding, it still appeared very lumpy. The edges are not expanding much and the mattress appears to be closer to 8-9", not 12" as advertised. I opted to sleep on the new mattress last night to test it out. This morning when I woke up, I felt I was sunken half-way into the mattress. I'm 6' and 215lbs. I've never had any issues with other mattresses in the past. The mattress is VERY soft, nowhere as firm or supportive as our Serta. I will give the mattress another 24 hours before returning it or contacting customer service to get any issues resolved.

My husband and I have been using this mattress for the last 3 months. Compared to our old mattress, I love it! It’s great for relaxing and so nice to sit up and read/watch tv without getting uncomfortable. I do like sleeping on it, but I’d prefer it to be much more firmer. I was not sold on memory foam for this reason. My biggest complaint is that it says it has a cooling feature. We have a mattress cover on top, so not sure if that takes away from the coolness? My biggest issue is that we both wake up extremely hot. We like to sleep with the AC turned down, so if we forget to do that, we will wake up HOT and sweaty. Overall it’s a great mattress, but not sure if I’d purchase for myself again.

After reading the negative and positive reviews for this mattress, I decided to give it a shot because we were in desperate need of a replacement. This mattress is advertised as a medium-firm mattress, but it is NOT that whatsoever. This mattress is SOFT... so soft that your entire body will sink in if you weigh over 150lbs. If you’re into that, then it may work for you. But if you bought a medium-firm mattress because you prefer medium-firm mattresses, you will be highly disappointed. If you prefer firm mattresses and thought you might just settle for a “medium-firm”, then you may fall into a deep depression. Believe me before you waste your money like I did... this mattress is nowhere near medium firm, or even medium. Also, prepare to have your room smell like chemicals for several days. We off-gassed and decompressed this thing for an entire day outside and the smell is still giving me headaches. Here’s to hoping I can return this thing!

Supposed to be medium firm, but there is NOTHING firm about it! Sit on side and sink all the way down. At least 2 inches wider than normal king. Yes, we let it setup before use, but it only rose to 10 inches. Box said 12! Should be labeled extra squishy! I want my old mattress back! Totally disappointed with this purchase! Btw won't allow me to give zero stars!

We're at day three on our Members Mark mattress, after returning a Casper mattress that we purchased. We found that the Casper was very stiff, and didn't breathe. On the flip side, this new mattress is super comfortable, and breathes well. It says cooling gel, but I haven't really felt cooling (It just has better airflow). For the price, I would recommend this to anyone.
