My son loves the comfort and the medium/firm feel. He sleeps well on his new mattress.

This bed has been comfy from the start. No break-in period. Sleeping better.

Visitors seem to think it’s comfortable. Not too soft and not too firm

Only had a few months and it has a big wrinkle in the mattress hurts my back to lay on it
