Replaces the pad, not covers it — and brings the wrench
A bolt-on replacement for cracked PU arm pads, cut for 4 in center-to-center mounting holes and supplied with M6 screws, washers and the wrench to fit them.
Podoy bolt-on PU replacement arm pads, 4 in spacing
Best for: A chair with 4 in hole centers and arm pads that have cracked through, where covering them up is not the answer.
Apart from the Ketofa pair, everything else on this shelf is a cushion that goes over the armrest. This is the part the armrest is made of. When a PU pad has cracked through to the bracket, padding it is a cosmetic answer; unbolting it and fitting a new one is the actual repair, and this hub’s whole introduction is about the measurement that decides whether you can.
Podoy publishes that measurement and repeats it: 4 in, 100 mm, center to center, and explicitly not 5 in or 5.5 in. It also publishes the second dimension that has to match, the underside bracket cutout at 5 7/8 by 1 7/8 in, and the thread size, M6 — which nothing else on this shelf states. The box holds two pads distinguished left and right, four screws, four washers and a wrench.
The honest caveat is what it leaves you with: solid PU, the same kind of hard pad as the one that failed — Podoy publishes no thickness or firmness, only that it resists cracking and wipes clean with a damp cloth. If the complaint is a sore elbow rather than a cracked pad, the memory foam cushions in this hub are the answer and this is not. And it has a near-twin alongside it — the Ketofa pads share the size, the cutout and the spacing, differing in that they ship with screws alone, at about $17 against $16 here.

From the center of one mounting hole to the center of the other, on the underside of the existing pad, with the pad off the chair. Podoy states the requirement twice, as a specification and again as an instruction: the pads are designed for a 4 in — 100 mm — hole spacing measured center to center, you are asked to measure before ordering, and the listing adds that they are "Not compatible with 5" or 5.5" mounting hole spacing." That is the single measurement this hub’s buying tip names, and this is one of only two listings on the shelf that publish it.
What is in the box. Both are 10 by 4 in PU pads cut for 4 in centers with a 5 7/8 by 1 7/8 in underside cutout, sold as a left-and-right pair, and both rule out 5 and 5.5 in spacings (Ketofa adds electric wheelchairs). Ketofa supplies four screws. Podoy supplies four screws, four washers and a wrench, and publishes the thread as M6. The two part numbers, 10U0509 and 10A0138, follow the same numbering scheme. On price the Podoy also reads about a dollar less, $16 against $17.
Memory foam pads that publish what most do not — a thickness, a firmness and the maximum armrest width they fit — with 13 in adjustable straps and a zip-off washable cover.
Best for: A standard task chair with narrow arms, where the pad should be firm enough not to bottom out.
Memory foam pads on a neoprene anti-slip base, with extra-long velcro straps the maker intends you to cut to length — the only listing in this hub that tells you to trim the straps.
Best for: An unusual armrest shape, where a fixed strap length is the thing that stops a pad fitting.
The longest pads in this hub at 11 in, with a stated fit window of 10.5 to 12.5 in — and word for word the same velvet caution as the 9.5 in Aloudy pads on this shelf.
Best for: A long armrest, between 10.5 and 12.5 in, where a short pad leaves the forearm hanging off the end.
Transparent dual-wheel polyurethane casters with a published noise figure of 28 decibels and a 700 lb rating — the second most modest load claim among the caster sets here, after the Lifelong's 650 lb.
Best for: A shared office or a quiet room, on a chair named in the listing.
Polyurethane rollerblade casters on industrial carbon steel frames with double-layer bearings — carrying a 2,000 lb claim that the same brand’s other set on this shelf puts at 700.
Best for: A heavy chair on mixed flooring, where the frame matters more than the headline number.
The plate that bolts under a chair seat and carries the tilt, swivel and height controls, published with the two dimensions that decide whether it fits — the cylinder hole and the bolt pattern.
Best for: A chair whose seat and base are sound but whose height lever or tilt has stopped working.
