    • Comfortable, compact, lightweight
Style: 5 Inch Size: Twin
This was purchased for my track day trailer. I lash it to the sidewall next to one of my bikes. I have had numerous injuries over my 50 years of motorcycle riding (not all from motorcycles) and an overnight at the track can be very uncomfortable. However this first time I tried this after allowing to open for several hours it felt like my bedroom mattress. Comfortable, cool the overnight low was close to 90, easy to move around. Good nights sleep was very welcome. Highly recommend for a small size. Perfect for a daybed, smaller room or a RV like my use. Great value, service and product. Looks like it will be with me for some time! ... show more

    • Perfect for top bunk
Style: 5 Inch Size: Twin
This was so thin when we took it out of the package, but followed instructions and let it re-fill for 2 days. Pleasantly surprised that it was 5" as stated. Great price! Perfect for the top bunk bed. My son says he loves sleeping up there now and it is so comfortable. We were looking for a comfortable, but not too thick mattress for the top bunk. ... show more

    • Nice mattress but….
Review Image by K.D
I’m just going to be honest. This is a good mattress . It expanded great and very well put together HOWEVER if you are looking for any give as far as softness, this mattress ain’t it. Medium firm is not what this mattress is…it’s feels straight firm. Don’t be fooled by the word “medium”. It took a few days for my body to get use to it. I will say though that after a few minutes the memory foam does take over and contours to the body ..not a drastic contour at all but I can tell it’s gel memory foam. If you are going to take a chance and purchase this mattress I would suggest getting a foam mattress topper, a mattress cover and a medium to firm large pillow to give it some softness and more comfort. That’s what saved me. Before I bought those additional things I would wake up with neck and back pain. IF you are looking for a mattress that’s just firm then you will like this one. ... show more

    • Great value and works great in our camper.
Great value for the money, we used this in our camper and cut it to size. The thickness was perfect since it's a popup and there was no smell with the mattress. It supports us especially me being a bigger guy. Seems to be good quality and this is the second one we have bought and the 1st one is still holding up well. ... show more

    • Like sleeping on the floor
I bought this mattress for my 3 year olds loft bed. I was pleased with the size and thought everything was great until she had a bad dream and wanted me to sleep with her. I think sleeping on the carpet would have been more comfortable, I laid there at 2 o'clock in the morning thinking about running it over repeatedly to make it a bit more softer. I could no longer handle another minute of this mattress or the back pain that would follow the next day so we moved to my bed. I feel awful that I’ve had her sleeping on this for the last few weeks. Medium firm… try concrete firm! 10/10 do not recommend unless you just enjoy sleeping on the floor, if that’s the case you can have this one! ... show more

    • Great mattress!
Style: 5 Inch Size: Twin
We bought this for our oldest son’s trundle bed and it’s a perfect fit. Very comfortable and will be buying more when our younger kids move to bigger beds. The mattress has no weird smell and it supports just fine.

    • Great mattress! 🤍✨
The media could not be loaded. I got two of these mattresses from my short term rental property and they are so comfortable and everyone loves them. It’s crazy to think that such a great mattress fit in such a small box! Highly recommend! 🤍✨
