We have 2 booster seats (grey) that are still in great shape. Selling as a pair if at all possible.

Olli is an award-winning belt-positioning backless booster. It says to your 6-12 year-old that it’s still cool to be safe in the car. Olli boosts your child’s height ensuring that the vehicle’s seat belt fits them just right while an additional layer of padding eliminates numb-bum syndrome. Easily transportable from vehicle to vehicle and especially handy while traveling from airport to rental car or even the taxi.
The Clek LATCH system locks the booster seat into place quickly and easily using your vehicle’s LATCH anchorage system.

LATCH (Lower Anchor and Tethers for Children) refers to the pair of fixed lower anchors built into the crease between the seat back and seat cushion. LATCH comes standard in some vehicles manufactured in 2001 and 2002 and all vehicles in 2003 and newer.

If your vehicle does not have a LATCH anchorage system, you can still use Olli unlatched.

Happy to answer any other questions as well.
