Really big and comfortable I would not inflate too much for an adult as due to the weight it may puncture it so I would put less air in as it makes it less likely to pop and it is more comfortable that way my only concern is the pvc is very thin so easy to puncture
Bought this to use in a Santa grotto nice comfy chair for Santa . Trying to make the grotto as magical as possible for the children so this fits perfect as everyone knows the gummy bears .Quality seams good although not used it yet .when not in use easy to stow away .
