  • For a bed in a box, its pretty good!
Size: Queen Style: 8-Inch Mattress
My child is in an efficiency while finishing college. I bought this because it is a great price and from a reputable brand. We will be disposing of this in 2 years, so why spend a lot? However, this bed is COMFORTABLE! It is on the firm side, but its a cozy firm. I'm really shocked at how good this mattress really is, I've considered getting a bigger one for my RV! It did not smell when I took it out of the plastic and we did give it 24 hours to inflate fully, but I don't believe that it took that much time. I recommend this mattress for dorm rooms, guest bedrooms, trundle beds, etc.... ... show more

  • Shockingly Good Trundle Mattress -Adults
Size: Twin Style: 6-Inch Mattress
I bought this for my daughters room so that we would have an extra bed for when company comes. This was intended for kids or smaller teens. Well Christmas rolls around and my husband has covid. Not wanting to sleep in my office I decide to try the trundle. I am 5’9 and not small. This bed is actually comfortable. I have joint and back issues and have had no problems. I am a side sleeper and while I wish it could be a 1/2” deeper (it can’t be because it’s obviously got to fit under her bed) it is still comfortable and I have woken up not feeling like I slept on my kids floor for 4 nights thus far. I am happy to know when offering this as a sleeping option to guests in the future that it’s comfortable and honestly possibly more comfortable than some of my kids normal mattresses. ... show more

  • Great thin mattress
Size: Twin Style: 6-Inch Mattress
I needed a thin mattress for my kids' bunk beds and went with this one. So glad I did. I lay with them at bedtime and I'm more comfortable than on my own pricey mattress! And thin enough to be safe for a top bunk. Replacing my other kiddo's crappy mattress with this one now.

  • 4" too short
Size: Twin Style: 6-Inch Mattress
We boguht the 6" mattress for our 4 year old son's bottom bunk. The comfort and support was fine for him but the length was still 4" too short after 1 week of letting it air out. Which was a bummer because the mattress itself is a nice mattress and 6" mattresses are a little harder to come by. Amazon was good about returning it in our case. ... show more

  • One year - then sleeping in a ditch.
Size: Twin Style: 8-Inch Mattress
This will have been my 4th, foam-type mattress. I am 5-10 x 165 lbs. It was comfortable 'till 'it was not. Like a slow drip, it kept taking a deeper set with time. I use a thin topper and sleep in the same position. This was firmer than the other foamies I bought here; which was Ok to start. I did my usual tricks: rotate it, but my waist is always near the center. It's too narrow to sleep near the edges. My final trick is to flip it over. This one was pretty stiff--for about three days. I now have a fairly comfortable gulley as the stiff bottom foam seems to be settling into the dead zone formed in what was the 'top. Once that bottoms out, I will be on the hunt for a 24mo. solution.
