This Spa booster seat is designed to be filled with water and the firmness and height of seat can be adjusted by amount of water used to fill it.
Made of durable heavy duty heat resistant material and can easily be filled with a standard garden hose.
Approximate dimensions filled are 14.8"x 3.8" x 14.2"
Please note:
Suction cups work best in spas with a smooth acrylic surface, they will not suction or keep the seat down if the spa has a textured acrylic surface. Not suitable for inflatable spas, rubber molded spas, soft tubs or any other spas with air bubbler jets on the seating areas as the air bubbling jets will push the cushions around even with a person sitting on it.
