If you have a highly developed sense of smell, yes, you will smell this for about 10 days. After that time I took all the bedding and washed it again, and now I don't smell it. I bought this to replace the water mattress on the guest Queen bed. I couldn't be happier. Now it will be easy to move the bed around and maintenance will be a breeze. I took the recommendation of an online advice blog about what to buy to replace a water mattress. I could have a longer replacement mattress custom made for big bucks or just buy a Queen mattress. The recommendation was to just buy a Queen mattress. In this day and age of over the top ridiculous mattress prices I was happy to find this one. It's fascinating to watch this thing expand from a tightly packed 'roll' into the bed frame. Make no mistake, it did leave a gap at the end of the mattress box. I filled this in with 3 old flattened pillows stuffed into the end. This bed is in our office and I like to plop down and chat with Hubby while he's working. I do wish it were a mite softer. (I'm used to plopping down in a water cushion), but all in all am thrilled to find that this works very well.

This twin mattress is for my husband's office - for napping and for sleeping when he has a migraine or a particularly bad snore night! I was skeptical due to it being only 1 mattress with no box springs. However it is soft but firm enough so you're not sinking in the middle. My husband put a couple of more slats under it too. Delivery was on the day promised which was a plus. I would recommend this mattress to anyone.

It is hard to describe it is extremely comfortable with no jiggle factor. We purchased for our 7 yr old and he sleeps through the night now. Yeah . Sometimes I share with him til he falls asleep and you don't sink but still feels firm and pillowy/cushiony. We love it, I hope it comes in a full size for our bed.

This is our second Night Therapy mattress. My husband and I bought the 10" King and loved it! We bought the 8" twin for my son and my girls are asking when they get theirs! This is the most comfortable mattress we've ever owned...and a great value! My family highly recommends this mattress!

[This review was collected as part of a promotion.] This twin mattress slides sometimes but it made my mattress feel softer. I’ve purchased a box mattresses before & it’s neat how it’s packaged and transformed. Once removed from its packaging & plastic it starts to inflate. I don’t know how long it took to get to it’s mattress size, but it took longer than any other mattress I’ve had. Usually the mattress reaches its inflated max size within seconds to a minute. But with this one I had to actually walk away & run some errands & come back to check if the mattress had finished inflating. This may not be with all mattresses but mine took its time. But when I got back it was inflated . Since I did not sit & watch it I can’t say as to how long it actually took. But it was more than 10 minutes at least. It’s easy to move- not too heavy. One person can maneuver it. Now if you need a firm mattress, this is not the one for you. But if you prefer a softer touch to your mattress you may like this one.

This mattress is so comfortable and I absolutely love it! For the first time ever I am sleeping through the night and waking up feeling refreshed. The price is so good as well. In my research I have found memory foam mattresses for $1000 or more. The only thing I noticed is that it is actually 7" not 8" but still very comfortable and would highly recommend.

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 was a gift for my son who is in the Air Force. Their mattresses are horrible and my son has a lot of back problems. I had this mattress sent directly to his address on base, and he says it's extremely comfortable. So far he has been waking up without back pain.

Was looking for mattress for my son's bed - didn't feel like going through hassle of ordering regular mattress so I checked Sams online and found this mattress. This mattress exceeded all my expectations - its comfortable, strong, and perfect for a good sleep!!

We've had the mattress for a couple of weeks now. I ordered this for my 9 year old niece. It came exactly as said and received rather quickly. We put the mattress flat for 48 hours and it only rose to 7", so I am not sure that it could be advertised as a full 8" mattress. I personally have not slept on the mattress myself. Overall, my niece seems to like the mattress and sleeps well.
