mine sprung a leak [SEP] i had to update my review because my cushion sprung a leak the larger section somehow water got inside and soaked the foam i cut that part off carefully trimming the vinyl skin so as not to disturb the seam between the large section and the small head rest section so now i have just the head rest which has two suction cups it is all i really need anyway original review my tub is a standard with tile walls on three sides so i was looking for something minimal that would not take up much space this one worked out great for me i put it so that the top edge of the cushion is right at where my tub tops out and meets the wall now i have something comfortable for my spine when i am sitting more upright and for my shoulders and neck and head when i slide down
