A tube slide is simply a slide in the form of a tube. It can also curve or have bumps. A straight slide is a flat slide that just goes down at a slight angle. A roller slide is a slide made of horizontal cylinders which spin underneath the person sliding as they travel down.They are made of brightly coloured plastic. Their versatility and appeal mean that they're well-suited for both indoor and outdoor use. As tube slides are constructed from several different segments, they can be designed in almost any shape or configuration desirable.
