Those were the first words out of my mouth this morning. This was my first night to sleep on this mattress. I had decided this was not going to work when I unpacked it. I thought oh well, I will at least sleep on it one night. Then I woke up and said, what just happened? I slept all night, I do not think I even moved or changed positions. I had no aches and pains. I will come back in a few months and update this review. If this continues for me, it is life changing. Maybe it is too soon, but I have not slept like that in years.

We have owned this mattress a couple of weeks. We ordered it for our 3 year old son. So far, we like it a lot! Very comfortable and a good buy for the money. After reading some reviews on other sizes/styles of the Night Therapy brand, I am a little concerned about how long the mattress will hold up without forming indentions, but for now, it's a great product. One further con: It did have a chemical smell (STRONG) upon opening the package, but the smell has weakened over time, though at 2 weeks, I can still smell it when lying on the mattress.

Great price and no springs. My son no longer has a desire to jump on his bed (what ruined his last mattress). Comes in a box rolled up, but was ready to use in seconds. Smell is a little annoying, but what do you expect from a foam mattress...the stuff isn't grown naturally you know. It went away soon enough...a few sprays of Fabreze helped. Great deal. Unless you're willing to part with a lot more money for the likes of Temperpedic, Sleep Number or Heavenly Bed, this will work. He'll be grown and out of the house by the time this mattress has outlived it's usefulness!

[This review was collected as part of a promotion.] My son (110 lbs) has been using this mattress for almost 3 weeks now. There is zero dipping or denting. My husband and I were so impressed with the firmness of the twin size mattress my son has been using that we purchased a king size for ourselves. We had just bought a standard mattress less than a year ago and with a few weeks we noticed dipping that did not bounce back. It amazes me that a memory foam mattress fared better than that. Our entire family is beyond pleased with the quality of Zinus memory foam mattresses.

I bought this one for my son and one for my daughter, we all love it. I have used different Memory Foam Mattress and this one is very comfortable similar to more expensive ones. Also the smell was completely gone in about 8 hours (other ones took months). This is top quality for the price.

[This review was collected as part of a promotion.] Got this for my boys since it was time for a new mattress anyways and they love it. It's very soft and alot more comfortable than even our new mattress. I've been tempted to use it a few times and I'm way too big for a twin size that's how comfortable it is. Even though we just bought a new mattress since feeling this one I may decide to order one just like this in a queen size. I would definitely recommend this.

Bought this for my 13 year old who has sleeping issues and adhd... he sleeps better he gets up less times at night. I've flopped on his bed a few times to bug him and have been shocked how comfortable it is. I was worried 8 inches wasn't going to be enough but my mother was right this mattress is perfect:

Took a chance and ordered this online for my daughter. I read all the reviews and the majority was good. It's soft and it really conforms to your body. I wouldn't say it's firm, more medium/soft. We've only had it for about 2 weeks so I can't judge the longevity or quality of the mattress yet. Maybe I can update my review further down the road. My daughter loves it so far.

We ordered this for our son who lives out of town. He got it quicker than expected. My son said he just pulled it out of the box, let it magically take shape and it was ready to be used on his new Classic Dream Steel Box Spring Replacement - Full Size that we also purchased online from Sam's Club. He athletically built and weight about 150 (all muscle) and said he sleeps like a baby on it. He even had a "girl friend" sleep over and said they slept very comfortably. He had no complaints what so ever. Our son's roommate got tired of hearing how much of a good nights sleep our son was getting that he asked if he could order one for him as well and he'd pay us since he doesn't have a Sam's account. We got him his bed 2 weeks later and loves his too!!!

I never seen in my life better than this comfort. Specially price and quality and really awsome. If you see price wise look like free this mattress. I can't believe it until i see in my eyes.
