Cleanup drives the design of this 6-in-1 highchair: the BPA-free PP tray goes in the dishwasher, the padded cushion pulls off for washing, and the frame wipes down with any household spray. Six setups come out of one chassis, from a tall seat pulled up to the counter down to a toddler-height desk with its own stool. The harness, front guard, and grip pads under a wide-stance base handle up to 55 lb across 6 to 36 months of use. It ships flat and needs no tools.
