Bought for handicapped son after he grew out of UK big Maclarens. Brilliant piece of kit, large enough wheels so that it can go almost anywhere (not sand) in comfort. Used but sturdy and clean, max weight of occupant is 68kg/10.7 stone. Folds in half, all three wheels come off with quick release levers for storage or to go in the car. Integral safety harness.
