The Sparco Universal Backrest Cushion (part 1023) is a fabric pad that fits against the backrest of a bucket seat or reclining sport seat. At £29, it adds a layer of lumbar and lower back support without modifying the seat itself.
The cushion is black fabric and described by Sparco as universal, meaning it is not moulded to a specific seat model. It attaches to the seat without requiring any permanent fixing.
The main use case is for drivers who find their current seat too shallow in the lumbar area, or who want to bring the backrest surface slightly closer when running a seat that is sized at the upper end of their fit range. It is not a substitute for choosing the right seat in the first place, but it can make a seat that is marginally too large in the backrest work more comfortably for everyday use or track days where total lateral support is not the priority.
Sparco do not publish dimensions for this cushion on their accessible product listings. If you need exact measurements before ordering, get in touch and we will check what is available from the supplier.
At £29, this is a low-cost adjustment for a seat fit issue before committing to a different seat entirely.
