Converting any chair or upholstered chair to a glider has it's limitations. That is, the chair must have adequate room under the seat cushion to set much of the glider unit UP INSIDE the chair or the chair will be too high.
Some, but not all chairs have this capability. The installer must install adequate blocking (wood support) to attach the glider/rocker supports. Naturally, this takes some skill and woodworking knowledge.
We have no additional installation information.
