Heated Seat and Lumbar Cushion with Dual-Zone Warmth
A seat cushion is sat on for an hour at a time, which is a different problem from a pad that is laid on a surface. This build treats the strap as a structural part, sets a separate zone map for the back and the seat, and specifies a foam grade against warmed load rather than room-temperature firmness.
- Separate zone maps for the back panel and the seat panel, not one map for both
- Foam grade approved on a warmed loaded test rather than a room-temperature squeeze
- Strap tension, anchor points and bar-tack reinforcement written into the tech pack
- Element kept out of the seat-bone load zone and off the fold at the seat-to-back transition
- Removable cover for washing, with the foam core and element staying with the structure
