Good quality and price!

the mattress is very good! It comes in a vertical box, so all you have to do is just cut the plastic and it will roll out. Naturally it takes a bit of time to fully expand, but not a long wait. very good for the price.

Great mattress- great humor!

Mattress is great. Everything turned out great. I have to give props to whoever wrote the directions on this thing! Not that I needed it- but it got a few chuckles from the family! Well done!

Good Mattress!

This is a good mattress, especially for the price. I got this because my kids took over my queen mattress and I got sick of sleeping on the floor! Lol. My dog cuddles up with me and sleeps on it too. I've been sleeping a lot better. If you're looking for a simple sleeping solution that doesn't cost too much, this one is perfect.
