Quick Answer
SA buyers should pay more for the right seat size before weight rating in most cases, because a seat that fits your frame determines comfort over hours, while weight rating only matters near the chair's limit. A R3,000-R5,500 chair with a seat width and depth that suit your build, plus an adequate weight rating, beats a cheaper chair that is too narrow or too deep.
Seat Size Versus Weight Rating, Decided
Both matter, but to different buyers. Seat size, the width and depth of the seat base, affects comfort for everyone every session: too narrow and the bolsters dig in, too deep and you cannot use the backrest properly. Weight rating only becomes decisive if you are near the chair's limit, where the gas lift and base are stressed. So for most buyers within a chair's weight range, getting the seat dimensions right for your frame is the bigger comfort factor and earns the premium.
Getting The Seat Dimensions Right
Check seat width against your hips with room to spare, and seat depth so that with your back against the rest, there is a small gap behind your knees. Racing-style chairs have raised side bolsters that suit slimmer frames but dig into broader ones, where a flat-seat or ergonomic chair fits better. A R3,000-R5,500 chair sized to your build is comfortable for long sessions; a mis-sized chair is not, regardless of price. Measure or sit in one before buying where you can.
When Weight Rating Leads
Weight rating should lead only when you are near or above a typical chair's limit, since then it governs safety and how long the gas lift and base last. In that case, choose a chair rated comfortably above your weight with a Class 4 cylinder and a reinforced base first, then pick the best-fitting seat within that range. For everyone comfortably inside a standard rating, seat size is the priority and weight rating is a box to confirm.
