Arrived ahead of the estimated delivery date. Because it arrives rolled up it was simple to install in the RV. Had almost no odor and inflated quickly. Checked on it the next day and it was up to 7 3/4 inches high. Could not detect any odor the 3rd day it was in the RV. Have not had a chance to sleep on it overnight, but it felt very comfortable laying on it for about 1/2 hour.

I bought this mattress for a daybed I had purchased. I have been using the mattress for about a week. It is comfortable and serving its purpose. I often have trouble sleeping through the night and am still having that problem but it is not the fault of the mattress. I hope to be able to report more after a few good "full" nights sleep. I was pleased not to have any odor as some had said they had. I also didn't have any trouble with the shape filling in. No problems at all. I am a satisfied customer.

My son needed a new mattress. I searched online and in many stores for affordable options. Some did come in slightly lower than this mattress, but they were half as thick, or not memory foam at all. I wanted him to have a nice memory foam mattress that could last through middle school and high school. NOTHING this nice was offered at this price anywhere else. When it arrived, I let it expand on the living room floor. My husband asked how it felt, so I went to try it in order to report to him at work if it was worth the purchase. I have trouble sleeping. He arrived home to me passed out for four hours in the living room on this twin mattress. No smell from the foam, expanded within 5 minutes, best mattress I had ever slept on till the 12" version of this came the next day for our bed. This mattress is not as extremely firm as the 12" pressure relief version we chose, which makes it perfect for our 11-year-old son. I would recommend this mattress to anyone who would not like the firmer option but dislikes the sinking into a pile of squish that the softer mattresses offer. It is a nice Goldilocks balance.

We purchased these for our two teenage boys and they are amazing! Anyone considering purchasing this mattress should! I was leery at first because the price seemed to good to believe but when they got here I was so pleased! This was absolutely one of the best purchases I have ever made from Sams!

I bought this mattress for use in my motorhome. I have a top manufacture brand memory foam mattress that I sleep on at home every night. I decided to save some money and buy this much less expensive brand. After sleeping on this mattress for the last week while on a camping trip - I have to say that the comfort level is almost equal to that of the top brand. The only difference is I think this brand retains more heat than the one I have at home. If you're looking for comfort at an affordable price (and don't mind being warm), this is a great mattress. Sweet dreams!

We made my son a loft bed and needed something that would give him the support and comfort of a pillow top mattress....this foam mattress did just that. He loves it. There was no smell and it was full size in no time. The top layer keeps my teenage son nice and cool. Great choice after a month of shopping. Priced perfectly.

Let me preface this by saying that I already had a high quality 4" memory foam mattress topper purchased from a different website, so I bought this relatively thin mattress because I knew I would be adding 4 inches of memory foam to it. That being said, this combo makes for a very good night's sleep.

I think it is a good quality mattress and I like the zip off mattress cover so it can be washed. I bought it for my Saint Bernard to sleep on. Large dog beds can cost well over $100.00 and they are usually made from egg crate foam which is not much cushion for a 160 lb dog. It is also much easier to change a fitted sheet then it is to take a cover off of a dog bed. I think it is a good mattress for dogs or people. I have not slept on the mattress but I have sat on it and it is a firm mattress.

I am currently working on the road and the mattress that was in my 5th wheel was shot. This mattress is working perfect as a replacement and I didn't have to spend a bunch of money to get it. Plus, the way it was packaged made it very easy to put in place. Very comfortable.

I just have to say the "off gassing" mentioned in the single bad review you see here is something that lasts about 24 hours. I'm asthmatic and have allergies and would be the first to say if a smell or chemical were a problem. In fact this mattress is the most amazing comfortable thing EVER and the slight smell that comes with the initial opening of the package is gone forever after the first 1-3 days. By the way I have bought this same thing 3 times for myself and then Queens for my 2 children.
