The weight makes it harder to change between positions, and the stays are plastic that can be felt when pushing down, but not really with general use. It hasn't gone flat or lumpy yet even when moved up and down often. (6 months of daily use)Normal queen sheets fit fine, although it's not as thick as a regular mattress. High quality as far as any futon mattress is likely to be.
