This mattress was bought for a guest room bed. However, I have slept on it as well, and I must say, it is very comfortable. It arrived quickly, was easy to set up, and I couldn't be happier with the result.

I'm a full time RVer and bought this for my travel trailer. It took longer to get the old one out than it did to get this new one set up. Took it out of the box and set it on the bed platform. (still wrapped) Removed the outer plastic so the mattress could unroll. (still vacuum sealed) Once in place, used the provided safety blade to open the vacuum plastic and the mattress immediately began inflating. Once all of the plastic was off, the mattress was almost at full size already. Maybe at 7 inches on a 10 inch mattress. Could have slept on it right there, if I had to. Went to bed about 4 hours later and it was probably close to full inflation. Much softer than my old mattress so it took a little getting used to. Not accustomed to the sinking and rolling feeling. But it was not excessive nor uncomfortable. Still plenty of support for a heavy guy once I picked a sleeping position. In fact, I haven't slept this well in a long time. And to wake up NOT sore was a blessing. This is a great product and I'm very happy with my purchase.

Bought this for my 4-year-old daughter's room and it absolutely is so comfortable This is the best mattress you can buy for the size of it It works great it's fresh and deflates pretty fast and the shape of it so far over the past year is still like brand new. We have that adults sleep in the bed many times as well and it still holds its form.

Arrived very quickly, very heavy single box- but they included the tool that made cutting open the wrap easy. Do not skip the tool it will keep you from destroying your mattress and sanity! I purchased 2 queens and they were good which is why i went back for the long! This is a very soft mattress-as in when sitting on the edge of the mattress it provides little support. That said we don't buy mattresses for sitting and it sleeps great as long as you don't need a firm mattress. It's a fantastic value for the price though after buying I decided to add a box spring because of the type of bed I have. However it doesn't need it!

I read the reviews prior to ordering and took a gamble but it totally was a smart move ! Yes there was some black specs inside the packaging that brushed right off , was not organic . Followed the instructions it waz easy to open. Let it sit and eventually it expanded to complete measurements plus. Super comfortable and fits perfectly in the camper! I layed a notebook on the top and measured from the highest point to the bottom and its closer to 12.5". Totally recommend for anyone! Im a big guy and it totally supports me and is very comfortable! No odor either maybe a slight new smell but its faded out already.

For the price, the quality is decent. There is no smell which is nice. Not terribly heavy, easy to set up. I get pretty good sleep on it, but can be a little lumpy bumpy. Height was as advertised. If you’re looking for a low cost spring mattress option, this one’s okay.
