A nestable cart has a generally flat base or platform supported on caster wheels and having sides which taper inwardly from the rear end to the front end of the platform. An upwardly extending handle frame extends upwardly from the rear end of the cart. An open area beneath the platform is designed to receive the front end of a platform of a second cart in order to nest two carts together. A nesting guide formation is provided at one end of the platform to guide two platforms into nesting engagement while lifting the rear wheels of a front cart from the ground during nesting of a rear cart into the front cart. The guide formation may be one or more rotating members such as rollers or guide wheels.
