Ergochair ERGO-RS Rolling Work Seat The ERGO-RS has six locking heights and it locks automatically. Those two facts, taken together, are the reason to choose it over a gas-lift stool, and they are worth understanding before anything else on this page. There is no lever to keep hold of and no collar to tighten: you lift the seat to the height you want, it stops at a defined position, and it stays there under load. A seat height that cannot creep down over an afternoon is a seat you stop thinking about. The travel runs from 5 to 21 inches, which is a wide span for shop seating and is what allows one unit to work as a chair and as a creeper. At the low end you are down where a floor creeper would put you but with a backrest behind you; at the top you are at bench and workbench height. The unit rides on four heavy-duty ball-bearing swivel casters and needs no assembly — it comes out of the packaging ready to sit on, which for a workshop tool is not a small thing. Six defined heights beats infinite adjustment Continuously adjustable seating sounds better on paper than it is in a workshop. Infinite adjustment means every setting is approximate, nothing is repeatable, and the mechanism holding it is a friction device that eventually stops holding. Defined locking positions mean the technician learns which position suits which job and returns to it, and the load is carried by a positive stop rather than by clamping force. The automatic part matters just as much. Any adjustment that requires two hands is an adjustment made once and then endured, because a technician holding a part in one hand will not put it down to alter a chair. Easy-lift height change with automatic locking is the difference between a seat with a range and a seat whose range gets used. Built to be sat on hard: 350 lbs and a welded frame The rated capacity is 350 lbs. That is not only about who can sit on it — it is about what happens when someone drops onto it, when it takes a shoulder as a brace while a bolt is being fought, or when a technician sits on the front edge and leans out. Shop seating rarely fails under a static load; it fails under the shock and off-axis loads that shop work applies constantly. The frame is welded steel tube, powder coated. Welded rather than bolted matters because bolted joints in a rolling, flexing frame work loose, and a loose joint is the start of a wobble that ends in a failure. Powder coat is the finish that survives being kicked, scraped along a jack stand and splashed with solvent, which paint does not. Casters: 3 inches, TPR, ball-bearing Each of the four casters measures 3 inches in diameter. Wheel diameter is the single specification that decides whether a rolling seat crosses a shop floor or gets stopped by it: a larger wheel rolls over a cord, a socket or an expansion joint that a small wheel jams against. Three inches is a working diameter rather than a furniture one. The compound is TPR, which is doing three jobs at once. It absorbs shock, so the ride across a rough floor is cushioned instead of transmitted. It is kinder to a coated or sealed floor than a hard wheel, which is worth knowing in a showroom-clean workshop. And it runs quietly, which sounds like a comfort point until you have spent a day next to hard casters chattering over joints. TPR is also resistant to chemicals, acids, alcohol and water — the everyday chemistry of a floor that gets brake cleaner, coolant and wash-down on it. The upholstery is chosen for the environment The seat and backrest are thickly padded and covered in heavy-duty non-slip textured marine-grade vinyl. Marine-grade means the material is specified to cope with sun, water and repeated soaking without the surface breaking down or the seams splitting — a workshop applies a different set of insults but the same requirement for the covering not to crack after a season. The non-slip texture is the part that supports the ergonomics. If the surface is slick, you slide forward every time you push back against the backrest, which cancels out the support the backrest is there to give. The backrest itself adjusts up, down, back and front, so it can be set behind your lumbar spine rather than wherever the factory left it, and the whole unit rolls in every position — raised, reclined or lowered. Perfect For Car and motorcycle technicians doing repetitive work at wheel and sill height, where the alternative is a bucket, a crouch, or a creeper with no back support. Aircraft mechanics, who work in awkward sustained positions and need to reposition constantly without standing up. Heavy equipment technicians, where the 350 lbs rating and a welded frame matter because the seat gets used as a brace as often as a seat. Factory and assembly line work. Repetitive stations are where posture damage accumulates fastest and where defined, repeatable seat heights pay back every day. Home garages and restoration projects, where the seat spends its life at the low end of the range and no assembly means it is usable the hour it arrives.

If a fleet policy, an insurer or a workplace assessment requires documentation covering shop furniture, raise it with us before you order and we will ask the manufacturer for whatever exists instead of leaving you to discover the answer later. Shipping and delivery Ships to the lower 48 states. Arrange for someone to be there to receive it, or choose to collect the shipment from the carrier terminal. Residential delivery carries a fee. This item ships free, so there is nothing to add at checkout. Look the shipment over before you sign for it: any damage to the carton, the frame or the upholstery has to be written on the bill of lading at the point of delivery, because a clean signature makes a claim extremely hard to pursue afterwards. Warranty The manufacturer's warranty applies. We have not put a term length in this copy because the product data we hold does not state one, and approximating a warranty period would undermine the point of the page — ask us and we will confirm the current terms. If something does fail, report it before dismantling it. A component that has already been taken apart cannot be properly assessed, and that is the usual reason a claim which should have been paid is refused.
