Design
Most modern shopping carts are made of metal or a combination of metal and plastic and have been designed to nest within each other in a line to facilitate collecting and moving many at one time and also to save on storage space. The carts can come in many sizes, with larger ones able to carry a child. There are also specialised carts designed for two children, and electric mobility scooters with baskets designed for disabled customers.
In the United States 24,000 children are injured each year in shopping carts. Some stores both in the USA and internationally have child-carrying carts that look like a car or van with a seat where a child can sit equipped with a steering wheel and sometimes a horn. Such "Car-Carts" or "Beans", as some call them in the cart business, may offer protection and convenience by keeping the child restrained, lower to the ground, protected from falling items, and amused.
Shopping carts are usually fitted with four wheels, however if any one wheel jams the cart can become difficult to handle. Most carts in the United States have swivel wheels at the front, while the rear wheels are fixed in orientation, while in Europe it is more common to have four swivel wheels.
An alternative to the shopping cart is a small hand-held shopping basket. A customer may prefer a basket for a small amount of merchandise. Small shops, where carts would be impractical, often supply only baskets.

Famous quotes containing the word design:
“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”
—Freeman Dyson (b. 1923)
“We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.”
—Joseph Addison (1672–1719)
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (1803–1882)
