So far, my kitties seem to like it.  Especially my male, he loves the sun. The bed appears a bit hard, but I think with time and weight, the surfaces will become more resiliant.  My female is a bit more finicky so she does not stay too long on the top bed.  Holds their combined weight of 15 lbs. just fine.

Pros: Easy to assemble and disassemble.  Nice feature to drop the bed in order to close the blinds or shutters.
