Multiple Purposes for Use: This durable multifunctional trolley box can be served as a shopping cart to load fruits and vegetables or carry many heavy items when shopping. Apart from this, it can not only be used as a step stool for easy access to high objects, but also as a chair to provide a stable seat for you to rest. Foldable Design to Save Space: This shopping cart with a hanging lid can be easily folded into a flat shape and is easy to store in the trunk, corners and garages. The utility cart weighs only 9 lbs, so it can be easily carried by hand. To transform it into a box shape, you just need to unfold it and slide the lock to fix it. Easy-to-climb Rear Wheels: The rear wheel is designed with oversized tri-wheels to easily go up or go down the stairs. When climbing stairs, there is no need to carry the shopping cart by hand. In order to maintain the service life of the cart, we recommend that the shopping cart must be in front of people when going down the stairs. Lockable 360° Swivel Front Wheels: This foldable trolley comes with front wheels that can rotate 360° without noise to achieve better control and change directions smoothly. What's more, the front wheels feature a lockable design that can prevent the car from sliding effectively when not in use. Durable Material for Great Bearing Capacity: The aluminium alloy handle with 3 adjustable heights can meet the needs of different heights. Made of impact-resistant PP, the utility cart features better bearing capacity. The load-bearing capacity is 88 lbs when carrying goods, and it can withstand 165 lbs as a chair.
