Unfortunately, I realized at this cushion that the dimensions specified by the manufacturer are widely understated. Very bad! Furthermore, the cushion of the presented "assembled" a bit tricky there. The sun loop needs to be connected to the cushion interior deck area in front of use. It happens by buttons and loops. The loops are very tight and fine. It's hard to get the buttons into the loops especially since you always have the feeling that if one moves on something that the loops come off the pillow ... All in all I'm really disappointed.
