Head on a roadtrip with your faithful friend safely strapped into the Cocoon. The Cocoon car (booster) seat is easily strapped into a seat by passing the seat belt through the rear vertical strap. If using the Cocoon as a booster seat is desired, an additional tether (extra leash set) can be attached to the rear D-rings and the tether looped around the headrest to hang as a booster seat to give your darling dog an exciting view of the open road. We always keep safety in mind which is why the Cocoon comes standard with an interior safety leash. Take your Cocoon basket with you on a stroll by simply removing the shoulder strap from one of the side pockets, attaching it to the basket and enjoy having your dog by your side. The Cocoon"s hard sides means that this is a durable basket that can safely carry the things you put inside, yet the bottom is soft enough, made of foam and PP board, to allow for furry passengers to enjoy a cushioned trip inside. Additionally, the Cocoon"s 70 denier nylon interior is water resistant and easily wipes clean with a damp cloth, allowing it to be used for many additional purposes, such as a portable grocery basket. By adding the KLICKfix handlebar adapter (sold separately), the Cocoon can also be used as a bicycle basket. The Cocoon is not suitable for air travel. Maximum loading capacity is 16 lbs/7 kgs or less.
