BIG RED TR6350 Rolling Pneumatic Creeper Seat

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 × 14.96 in). Seat adjusts 17.32–22.05 in via side lever; rated 250 lb. Four polyurethane-compound swivel casters (~2 in estimated; not manufacturer-disclosed); no locks. Vinyl padded seat; no backrest; PU foam assumed. Tray is seated-accessible, multiple compartments; no magnetic strip, no drain holes. 2,914 reviews / 4.5★, #31 in Garage Shop Roller Seats; 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 under 250 lb. Skip if primary work is under-vehicle (a mechanic creeper handles supine access) or user weight exceeds 250 lb.

Rated for seated use only — standing is outside the rated load distribution. Adjustable pneumatic stools can develop cylinder pressure-loss (seat sinks under load); monitor at 12 months against the 1-year warranty. Steel base, vinyl seat, PU casters — no chemical exposure pathway. Steel base and tray recycle at scrap; vinyl cover and foam do not.
