The suction cups are securely attached to the back of the cushion and will not detach. Durable suction cups provide grip on smooth tub surfaces. 2) Extra comfortable and ergonomic: The bath pillow is developed and optimized to relieve stiffness and tension in the neck and shoulder area. The two suction cups ensure the pillow sits firmly in the bath. The ergonomic groove design fits well with the natural contour of the back, offering good neck support and relaxation. 3) Material: Waterproof PU. The cushion does not require long drying or drainage; simply wipe dry with a cloth and store away. No unpleasant smell, quick drying, does not discolor in dyed bath water, and there is no need to wash the bath pillow regularly in a washing machine. Say goodbye to mould and bacteria. 4) Easy to install: Suction cups hold the cushion in place. Place the cushion in the desired position. Press firmly so that the suction cups seal. To remove, carefully pull on the individual suction cups. Suitable for adults and children. A necessity for people who like hot spring baths.
