Soft and firm. The backboard is very flimsy, and I doubt it will last long. Overall its not too bad, but the hardware used to mount the pieces together is several inches off from side to side, so there is a noticeable difference where the sides mount to the base of the couch. It does not functionally cause issues, so far at least, but does not give me great hopes about the construction quality. Would definitely spend the extra money for better furniture next time, and will avoid the brand if possible.
