Choosing between these two reclining seats comes down to whether you want a cool, rigid, and reliable setup or are willing to risk severe shipping delays for PU leather. The ERS5 Fabric & SimAero Mesh Edition delivers a highly breathable and stable experience, while the RS Adjustable Seat is plagued by customer service and flex issues.
Buyers of the RS Adjustable Seat frequently report severe shipping delays and poor communication from 6 Sigma, with some waiting months for delivery. Once it arrives, users often experience noticeable flex in the seat back, squeaking under heavy braking, and poorly aligned mounting brackets that make installation highly frustrating.
If you plan to mount the ERS5 Fabric & SimAero Mesh Edition to a third-party aluminum profile cockpit, be prepared for some manual measuring. Some users have noted that finding official mounting dimensions online can be surprisingly difficult.
The ERS5 Fabric & SimAero Mesh Edition is the undisputed choice here, offering a vastly superior ownership and driving experience. Its fabric and mesh design keeps you cool and comfortable during long sessions, completely avoiding the hot and sweaty feel of the PU leather found on the RS Adjustable Seat.
In terms of performance, its double-reclining mechanism provides impressive rigidity with minimal flex under heavy braking, whereas the RS suffers from noticeable back flex and squeaking. It also spares you from the frustrating installation issues and severe shipping delays associated with the 6 Sigma option.
For context, the ERS5 Fabric & SimAero Mesh Edition starts at $279.00, though its price history is too short to judge any long-term trends. Meanwhile, the RS Adjustable Seat is currently $329.00—a price that has remained unchanged over 90 days, despite a historical low of $199.00 on February 26, 2026.
