This chair is in good used condition. We have a smoke free home. The chair has 4 height adjustments positions -up and down. You can also recline the seat backwards. The chair folds flat as you can see in the picture. The tray is adjustable forward and backward to allow for more or less room in the seat. The wheels have locking mechanisms, too. The blue part of the tray is removable and dishwasher safe. The seat cover comes off and it can be washed. Porch pickup in Portland.
