The OXO Tot Perch Booster Seat with Straps boosts tots from 15 months up to the perfect table height on any grown-up chair. A 3-point harness with easy-to-adjust straps keeps tots secure in their seat and can be removed when your tot becomes a big kid (3+ years). Conveniently store Booster Straps underneath the Seat's cushion when not in use. The Perch Booster collapses quickly and easily for convenient travel and compact storage and a removable, soft cushion resists stains and is a cinch to clean. Non-skid feet keep Booster securely in place on any style sea. The Perch Booster is BPA, Phthalate and PVC free.
