Diono Radian RXT car seat. Used but in good condition. Apparently they don t put the manufacturing date on, but the website says they re good for harness mode up to 8 years and booster up to 10 (https://us.diono.com/before-you-buy/) We purchased in 2014 so this one should have quite a few more years. Can be used forward or rear facing. Pickup in Georgetown on 30th Street.
