Our kids highchair is made of thickened heavy duty stainless steel for durability, shock absorption and load bearing. Its seat is made of PP material that helps to provide fatigue resistance and provide maximum comfort. The sturdy construction provides comfort, stability and ergonomics for your baby. 4 in 1 products - baby high chairs, baby high chairs and trays, toddler chairs, and large children's tables and chairs to suit every stage of your child's growth. Keep your baby safe and comfortable with the 5-point harness. Easy-to-clean seat with wipeable EVA foam seat cushion. The straps wipe clean and are machine washable. Machine washable seat cushions make cleaning easy. Our high chair includes a double deck that also locks, so you only need to remove the upper deck for cleaning after your baby has eaten, and the lower deck also provides baby play space for your handy toys. There is also a telescopic design next to the seat, and three adjustable positions provide more space and flexibility for fast-growing children.
