Rather than just sit it on a regular chair I checked some measurements and decided to hack apart the old Poang for a proper seat.
How to make a POANG massage chair
Removing the rear arms-to-back bolts allows the seat to swing up so it isn’t in such a reclined position (too much stress on the massager I figured), and makes getting in and out easier (though I may still install 2 or 3″ risers on the bottom to raise the whole chair a little higher).
Took some thinking and fiddling around with scrap wood and clamps to get the angles and dimensions right so the ~5″ thick massage part would sit more or less flush with the existing chair rails, then some fairly complex angle cuts with a miter saw.
Materials used are 2×4 for the riser blocks, 3/4″x2″ oak for the main horizontal stringer to support the massager, 1/2×2″ poplar strips for the two supports bolted under the seat and also for the vertical back supports, and various 2″ and 3″ wood screws and gorilla glue to hold it together. More solid now than it ever was.
Finally gave the entire thing a light sanding and sprayed with “Colonial Red” primer/paint. Thought it would be a bit darker but looks good in our Asian themed bedroom.
Even with the foam removed from the back of the cover the double layer of corduroy does mute the massaging action somewhat. Still feels great, but if a more intense massage is desired the entire cover can be easily removed to put your back directly on the massager.
