Done After 6 Months!

We bought this mattress about six months ago. At first, it was fine. We had no issues. But now we both wake up with our backs hurting so bad. You sink into the mattress and there's a little support now that it's been used for six months. My husband says when you try to roll over it feels like rolling up a mountain because you sunk down so low into the mattress. I read the reviews and chose this mattress for the price and mostly positive reviews. I wish I would've went with something that was more expensive and better quality maybe it would've lasted longer than six months. We've already ordered a new mattress.

My wife loves this mattress

I, however, don't find it that great. Before we bought this mattress we had an adjustable air mattress. We had this mattress for 12 years and had no problems. When one side of the mattress became too soft or firm it was easily re-adjusted. This current mattress can't be adjusted and I find that it is too firm. Problem is, I can't re-adjust the firmness. I should have purchased a 14" mattress. I hear that the 14" is slightly less firm. Also, after about 3 weeks there is still an odor. This odor is not really objectionable, however, it smells like mold. At least to me. This concerns me. I had asked the manufacturer about this odor and received a non-reply. They said the odor should go away in no more than 3 days. OK, like I said, the odor isn't that strong, but it smells like mold. No one can, or will, tell me what the odor is supposed to smell like......plastic, rubber, mold, flowers....? As I stated earlier.....my Wife loves it ...so......I guess it's a keeper.

Love the mattress Not the smell

This mattress is very comfortable and just the right firmness for me. I have back and hip issues and sleep well on it. The only issue I have is with the smell or as they call it off gassing. Left it uncovered for some time but think that smell is going to be around for probably months.

Comfy. I can sleep on my side again!

I have been sleeping on this for about a month. I went from an old "spring" mattress to this memory foam. It was easy to set up and I was able to sleep on it the same night. I am able to sleep on my side again, something I had not been able to do for months since having problems with my shoulder. My sleep is definitely better and the price was reasonable.

Great Mattress

I am so happy with my purchase, what a deal for the money. The twin size mattress is exactly what I need for the daybed in the guest bedroom. It sleeps comfortable, better than my more expensive mattress. I will be purchasing another for my Queen size bed.

Happy Wife, Happy Life!

My wife's friend has a similar mattress and I found a great deal on Sams.com. The mattress was delivered in about one week and it was easy to install. I unpacked it and let it decompress for about two days. There wasn't much odor to the mattress so we quickly replaced our old mattress with it. My wife has been sleeping soundly every night since we got it, which is great because she was having problems with our old Sleep Number mattress.

Great night sleep!

I was skeptical at first when I saw how compressed it was at delivery. But after it came to shape and we set it up. Boy I was surprised how comfortable it was. I am a side sleeper with hips and knee pain. First night I slept so sound and woke up with much much less pain. Love it, wish I bought it years ago!

Disappointed

Five days after I opened the box and settled the matters on the bed it was only 6” when I was told to wait 72 hours to reach 12”. Also, one corner was missing a piece of the center foam, there was an empty space there. I don’t or can’t say the product is bad. What I’m expressing is that the one I received was not good.

So comfy

I’ve had it for a couple of weeks and i love it. Just as good quality as the mattress that costs thousands of dollars. It’s soft but has the right firmness. I love it my kids love it when they get on it. It’s heavy to get in the house and a bit difficult to take out of the package but worth it

Best mattress I have ever had

I was worried when this first came as it was slow to expand but it finally did after a few days. Easily the most comfortable mattress I have ever slept on. Had it for about five months now. I thought I really like my previous mattress until I got this one, I like a firm mattress and this one is firm but it has a level of softness to it that makes it absolutely perfect.
