The Shop-a-Seat Liberator is a four-wheeled shopping trolley that features a sturdy but discreet seat, which also functions as the lid to the shopping bag.Consequently, the user can take a rest whenever required, since the padded, waterproof seat is sturdy enough for people weighing up to 160kg (25 stone). Like the Shop-a-Seat Escort, it has a well insulated bag that functions like a cool bag, keeping perishable items cold while they are taken from the shops to the home.Other useful features include a sturdy fastener for security, high visibility reflective strips, and easy-folding handle and integrated metal feel for added stability when seated. The features that distinguish the Liberator from the Escort model include a height adjustable handle, thicker hand grips for people with arthritis and similar conditions, and a cord that enables the user to fold the product without having to bend down.
