Excellent Comfort and Support

This mattress is extremely comfortable with the perfect medium-firm feel. The gel memory foam helps keep it cool throughout the night. It provides great support without feeling too stiff or too soft. I wake up without back or shoulder pain since using it. Overall, it feels high quality and well worth the purchase.

Great mattress.

The box with this mattress is so heavy. It was difficult to bring into the house and then taking it out of the box and opening it up! It inflates really well. The mattress is very comfortable. I really like it. It was so nice to sleep on It's firm yet soft. I got a very good night's sleep on this mattress.

Highly recommend

This mattress is sooo nice! Step one, make sure it's the right side up lol. I could initially feel the springs and thought this is not going to be comfortable. Then realized it was upside down. When it's right side up, it's so comfortable! It takes a while to reach its full form, but I am able to lay on my back, get up and not have any back pain. I couldn't lay on my back without struggling to walk upright before my back pain went away with my other mattress. I was shocked!
