I was concerned due to some of the negative reviews but I'm glad I followed through with the purchase. For me the mattress has been the perfect combination of comfortable and firm. Some reviewers have said it's not a medium firm mattress. I don't know if that is true or not but the mattress has been firm enough for me...given that if I sleep on less firm mattresses the lack of support will cause me to have a discomfort.

[This review was collected as part of a promotion.] I was so excited to find this mattress, as I was in the market to upgrade my daughter's bed. She is growing and not only needed to move from a full size but also to a more supportive mattress that will last years. The Member's Mark brand is already a brand my family trusts and I was excited to gear about this new mattress! The mattress arrived quickly and was compacted in a box. It was quite heavy- 90 pounds actually! Opening the box was the toughest thing to do! This works best with two people- one to pull the mattress out and one to stabilize the large box. Once out of the box, you have to unravel several layers of plastic wrap. The mattress immediately began to expand. I placed it in my daughter's room- on top of her bunkie board bed frame and watched it open up to a 12" deep mattress! Wow! I left it alone for 48 hours as suggested in my box- but I believe it would have been completely expanded within a few hours. This mattress is dreamy- soft and durable material. This is a foam mattress, so your body feels cradled when you lay down but the support is very impressive. My daughter actually slept in the first night- something she never does- and said she felt amazing. After a few days of her bragging about this, I actually took a nap on this mattress and I'm totally jealous. This seriously feels like a soft cloud, but after sleeping you can feel that it is equally supportive. This is an amazing mattress from start to finish. You can easily set this up yourself. The quality is simply the best I have ever seen! I'm completely self on this and can't wait to get another for my son's room next! I see this lasting quite some time and this will be the last mattress I will ever get for my teenager!

[This review was collected as part of a promotion.] I’ve had my new mattress for two weeks. This mattress is really nice . It comes in a box and inflates within minutes of taking it out of the box. The style is very nice. I really like how it has a cooling mattress cover around the whole mattress . This mattress is not firm it’s the perfect memory foam mattress. It’s soft and really has helped me get an amazing full nights sleep since I started using it. My back and neck hurt much less than before having this mattress. This brand is really great! I can tell it’s durable and will be used a very long time. I’ve slept on a few mattresses this one is the best .

[This review was collected as part of a promotion.] The mattress came in an easy to move box to get into the house, unpacked and rolled out perfectly. This is a very comfortable mattress and is perfect in my guest bedroom. My guests absolutely love it.

[This review was collected as part of a promotion.] This mattress is absolutely fantastic ! Not too firm , perfect for a good nights sleep :) Came in a medium size box, the mattress expands after you open the packaging . We let it air out for a day , but did not notice a funny smell at all . A+ for comfort ! Highly recommend :)

[This review was collected as part of a promotion.] I've been sleeping on this 12 inch mattress for a few weeks now and am overall very happy with it. It came in a box and I really wasn't sure how comfortable it would be. After opening the box and taking the plastic off the bed took shape. I have a bad back and this mattress provides a supportive rest for me. It's more firm but also soft. It has provided some much needed sleep at night. Now I want to purchase one for my guest room. These are amazing quality and I'm sure will hold up for years. I'd highly recommend anyone looking for a new mattress to give this one a try.

[This review was collected as part of a promotion.] I bought this mattress for my bed , and sleep on it last night, it was so comfortable and breathable , I had a excellent sleep last night . The quality is very excellent, Just over all Very very great quality of mattress, my daughter took a nap in it yesterday and was in shock how comfortable and soothing it was now she placed her order yesterday for her own , I honestly highly recommend this Mattress.

I bought this mattress for my 6 year old son since the mattress he had was just too firm and uncomfortable, even with a memory foam mattress topper. I cannot believe how comfortable and great quality this mattress is! The mattress in my room was thousands and this $300 mattress is way more comfortable. Highly recommended!

[This review was collected as part of a promotion.] People like ranges from firm to soft beds. I like a medium firm bed and this fit exactly that. You can tell, on the first couple finches, that the material is memory foam-like. For back pain, you need a firm bed that maintains your back line. This bed was fantastic for that. A nice combination of comfortable and firm. Very easy to unpack and place on bed.

[This review was collected as part of a promotion.] I'm always curious about the quality of sleep I will get when I'm staying in a hotel, as it seems all of the mattresses are completely different. I wish every hotel had this mattress, though. It's comfortable, it's right in the middle-of-the-road as far as softness/firmness is concerned, it doesn't get too hot, nor do you freeze to death while sleeping. I'm very impressed with the quality and I look forward to getting many a good night's sleep on this mattress. My only potential concern is the longevity, but that's something we'll just have to find out in the long-term. If you're looking for something that is of good quality, comfortable, and not tailored to a very specific type of person, then I'd definitely recommend giving this mattress a try.
