This listing is ONLY for a set of four black o-rings. Our IKEA highchair adjustable footrest comes with a set of four so you only need to purchase this listing if you want a spare set (or if your spouse missed them in the package and accidentally threw them away 🙈). Also handy if you use an IKEA highchair at grandma's house and you only want to bring the wooden part of the footrest with you instead of taking the o-rings off your own chair each time.
Safety Warning: Please keep unused o-rings out of reach of children. The small rings are not a toy and could be a choking hazard.
