General Helpful Tips: Increasing Chair Height with a Platform Riser

🛠️ DIY Home Platform Riser: Adjusting Chair Height for Safety

In this video, Cindy demonstrates the construction and use of a homemade platform riser. This custom platform is a great option to help adapt the height of a favorite chair or recliner, making it easier and safer to get up and down due to generalized weakness or post-surgery restrictions (like knee or hip replacement).

Materials Needed
(1) 3/4 inch plywood

(2) 2×4 lumber pieces

(3) 1×1 trim pieces

(4) Wood screws

(5) Rubber shelf liner

Construction and Safety Instructions
(1) Measure: Measure the outside width and depth of the base or legs of the chair.
(2) Add for Trim: Be sure to add the additional length in each direction to accommodate the 1×1 trim piece, which will frame the top platform.
(3) Height Gain: This platform, using the suggested materials, will provide approximately 4 inches of additional height to the chair.
(4) Containment: The 1×1 trim is crucial; it is used to frame the top of the platform in order to prevent the chair from sliding off of the platform during use.
(5) Anti-Slip: Use rubber shelf liner as needed:
– On Top: Place the liner on top of the platform to help keep the chair from sliding on the platform.
– Beneath: Place liner beneath the platform (depending on the floor surface) to help keep the platform from sliding on the floor.
