  • Wonderfully Amazing
It has great comfort for my back

  • So comfortable!
Bought it for a guest bed and everyone who has slept on it says it is just the right firmness! Thought the price was reasonable. And it expanded for us as soon as we unwrapped it!

  • Firm yet bouncy
Firm giving me the support I need but still bouncy enough to be comfortable. Seems to be well made and the right size for me. Great for people on a budget that want a quality mattress.

  • Feels like my old one
It honestly feels like my old mattress I’ve had since I was born essentially and I’m pretty sure it’s older than me. This one was fun to set up tbh I wish they gave you a line to cut so you can roll it out before you open the actual packaging. Started inflating before we could put it on the bed frame so it’ll roll out well. I mean I would say it’s worth it but honestly I would go to a mattress store instead and see if there’s one there you like then order it on Amazon. It’s pretty firm but I like it. ... show more

  • Comfy Mattress
This mattress was very easy to open and set up. I have to say it is one of the most comfortable mattresses I have ever had. I would definitely purchase again.
