  • Comfy mattress
Medium firm mattress. Arrived quickly, and such a good value!

Very comfy

  • Not too soft or too firm. It's great 👍
So far this mattress is the best not only beautiful but we sleep so much better than any mattress I've owned. I don't know anybody else is in bed. Firmness is perfect.
