TL;DR 250 lb rated, 4-leg welded steel base, adjustable 17.32-22.05 in; PU-compound casters, diameter not confirmed. Vinyl seat, no backrest; session duration undocumented in community sample. 1-year cylinder warranty.
The TR6350 is an adjustable-height pneumatic creeper seat on a 4-leg welded steel base that doubles as a segmented tool tray (14.96 x 14.96 in). Seat adjusts 17.32-22.05 in via side lever; rated 250 lb. Four polyurethane-compound swivel casters (approximately 2 in estimated from imagery, not manufacturer-disclosed); no locks. Vinyl padded seat; no backrest. Tray is seated-accessible, multiple compartments; no magnetic strip, no drain holes. Highly rated on Amazon across a large owner base, with no widespread structural or cylinder-failure reports. The "300" on the cylinder label is a model-family designation; rated capacity is 250 lb.
Right pick for DIY wheel work, brake jobs, and low engine-bay access in the 17-22 in range for users under 250 lb. Skip if primary work is under-vehicle (a mechanic creeper handles supine access), if you're near or over 250 lb (a 300-400 lb rated stool is the safer choice), or if your work requires a height above 22 in.
The stool is rated for seated use only; standing on the seat to reach high shelves is outside its rated load distribution and not a tested use case. Adjustable-height pneumatic stools can develop a cylinder failure mode where the seat sinks under load; no widespread failure pattern is documented in the community sample, but the 1-year warranty is the limiting backing. No chemical exposure pathway: steel base, PU foam seat, polyurethane casters. The steel base and tray recycle through standard scrap metal programs; the vinyl cover, foam pad, and caster plastic do not.
The TR6350 is rated for 250 lb seated load per the Amazon feature bullets and product specification. The '300' visible on the cylinder label in product images is the TR-series model-family designation, not the weight rating.
17.32 in (minimum) to 22.05 in (maximum), a 4.73 in range, adjusted via a side-mounted pneumatic lever.
Four 360-degree swivel casters with orange/red polyurethane-compound wheels, confirmed from product imagery. No caster locks are included. Diameter is estimated at approximately 2 in from the spec image; not explicitly stated by the manufacturer.
No. The segmented steel tray holds tools by depth and compartment walls but has no magnetic strip.
A 1-year limited manufacturer warranty per Torin Jacks, Inc., covering the pneumatic cylinder and frame.
The Amazon listing for BIG RED TR6350 Rolling Pneumatic Creeper Seat carries a California Prop 65 warning. California requires this warning on a very wide range of manufactured goods — including rubber, vinyl, plastic, and metal automotive parts — whenever trace exposure to any of roughly 900 listed substances (commonly phthalates or heavy metals) is possible, regardless of whether the specific product poses a meaningful health risk. As a passive accessory, BIG RED TR6350 Rolling Pneumatic Creeper Seat has no Safety Data Sheet, so there's no chemistry breakdown to translate beyond that.
