?BOOSTER SEAT FOR TABLE UPGRADE - We added a thinner booster seat cushion to the toddler booster seat for dining table after receiving some feedbacks from customers. It means you can get 2 PCS child booster seat for dining table at the same time (3.3 inches and 1.8 inches thick). You can stack two booster cushions on top of each other to increase the height of the seat or put a thinner cushion front the chair to make it more comfortable for the child (the heightening effect can reach 5 inches). ?EASY TO WSHABLE - The surface of baby booster seat for table is made of high-quality waterproof PU leather,it is skin-friendly and waterproof. You only need to wipe it with a wet paper towel to clean it if the food accidentally falls on the booster pad. In addition the booster cushion has a zipper, easy to disassemble and clean. ?SECURITY UPGRADE -- Kalawen kids booster seat for dining table has 2 adjustable seat belts (13-32 inch or 17-30inch) and expands the fixing belts on both sides of the cushion, which can effectively fix the cushion to prevent the cushion from sliding and causing injury to the child. In addition, the bottom surface of the cushion is designed with non-slip points, which is safer.
