Popular arcade games such as Dance Dance Revolution, In the Groove, and Pump It Up use large steel dance platforms connected to the arcade cabinet, whereas console versions usually use soft plastic pads. These home pads are specifically made for systems such as the GameCube, Wii, Dreamcast (Japan only), PlayStation, PlayStation 2 and Xbox, but can also be used in computer simulators such as StepMania through the use of special adapters.
Some soft pads contain stiff foam inserts of the dense or hard varieties to provide more stability and durability. The inserts usually ship as three or six puzzle pieces (to allow for a smaller box) which fit together using a dovetail joint and slide into the dance pad, which then zips closed around the foam. Certain brands of foam pads put raised plastic sections under the directional buttons to allow them to be more easily felt by a player's feet, so as to help keep him centered on the pad. These pads generally cost between $40 and $100.
Hard pads are used in all arcade versions of music games that employ dance pads, and often serve as the nec plus ultra for DIY Gamers that attempt to construct Homebrew pads. Many Homebrew kits are ultimately instruction guides for converting soft pads into hard pads, although Homebrew hard pads often feature additional functions such as additional inputs (see below).
Not satisfied with the cost and/or reliability of factory assembled metal dance pads, many players construct their own dance pad. Using common materials (such as plywood, sheet metal, and acrylic glass or polycarbonate) found at local hardware stores), do-it-yourselfers are able to construct a pad that is often much more durable and more authentic-feeling than commercially built hard pads. Some homebrew pads have extra features such as additional arrows (for playing Pump It Up or DDR Solo), menu switches and pushbuttons, and bars. Furthermore, the homebrew pads are easier to repair because they use common parts, and are usually designed for easy disassembly.
