I have tall and bigger size boys and these beds are absolutely perfect. They are firm but not hard and the pillow top makes them feel amazing.

After sleeping on this for a about 2 weeks. Im happy with it. It is pretty firm. But not to bad. There no noise when laying on it or moving around. Its just the right thickness for me. Fit my frame just fine. Only thing I wish the corner didnt slope so much

Been sleeping on my new full size mattress for a couple weeks now and am super satisfied. It was at a great price and is really comfy. It had no smell like I had read about when buying boxes mattresses so I was stoked about that. I really needed it and am super grateful for the awesome deal. $134 for a full size mattress, ya can't beat that!!!

I bought this mattress for my grandbabies’ bunk bed, and they seem to really like it. It’s firm and the perfect height for the bunk bed. Plus, there was no unpleasant odor when I opened it.
