Contoured Memory Foam Lumbar Support Pillow
DETAILS
Add shaped lumbar support where a work seat lacks useful built-in lower-back contour. Designed for drivers and other seated workers, this portable memory foam cushion combines a tall back-support profile with sculpted lower wings and an integrated base for use on compatible vehicle seats and chairs.
- Contoured Lumbar Support: The tall sculpted profile adds a defined support surface behind the lower and mid-back instead of simply adding cushioning beneath the seat.
- Memory Foam Construction: Memory foam creates a cushioned interface between your back and the existing seat.
- Sculpted Lower Wings: Pronounced side contours create a broader shaped support area around the lower-back zone.
- Integrated Lower Base: The single-piece design extends onto the rear seat surface to create an integrated back-and-base support shape.
- Portable Between Seats: Move the cushion between compatible work vehicles, company vehicles and chairs when built-in lumbar support is limited.
Good For: Drivers and vehicle operators spending long periods seated in work trucks, fleet vehicles and other compatible work seating.

Footwear Size Guide
For the best fit, measure your foot length (cm) and use the chart below. If you're between sizes, we recommend sizing up.
How to Measure Your Foot
- Use a sheet of paper: Place it against a wall on a hard floor.
- Stand and mark: Heel lightly against the wall, mark your longest toe.
- Measure heel to toe: Measure the distance in cm.
- Measure both feet: Use the longer measurement.
- Wear your usual socks: If you’ll wear sports socks, measure with them on.
