Lockable swivel wheels are the practical difference here: the chair spins in place, rolls to wherever the meal is happening, then locks so a toddler cannot push it across the floor. Seven height levels put the seat between 20 in and 27 in and the tray between 28.5 in and 35.5 in, covering a low sofa table up to a tall kitchen counter. The double-layer tray has a molded cup slot, resists heat, and goes in the dishwasher, while the oil-resistant cushions shed grease. Fold the frame, clip the tray to the back, and the storage bag underneath keeps wipes on board. Rated 33 lb
