The Stokke Tripp Trapp is a popular, long-term investment that is easy to clean and requires no extra cushions for comfort. While the baby set attachment is highly recommended for younger infants, you can generally skip the optional seat and backrest cushions, as they often just add extra laundry. Regarding the tray, ergonomic height is the priority; if your dining table is at a similar height, you may not need the tray attachment at all, allowing your child to sit directly at the table with the family.
