I don’t much like it. While it is plenty fine for just sleeping, 10 inches is too thin, I should have done 12 or 14. It is also too low, so the bed is less nice for sitting and general lounging purposes.
Now I am leaning toward getting a California King bed frame and foam mattress. I liked the upgrade from twin to full, and from full to queen. I expect the upgrade to CalKing will be a positive too.
