Cabinmass builds aftermarket lumbar, cushion, and headrest kits that install in days — not the seven-year cycle of a full seat replacement program. Comfort that competes with business class, priced for economy.
Airlines won't rip out 4,000 economy seats they bought three years ago. So we built the inverse business: keep the shells, replace the surfaces passengers actually touch.
Cushions, lumbar inserts, headrests. No re-cert of the seat shell — only the surface kit.
A 162-seat narrowbody completes overnight maintenance with kit installed the same week.
STCs in hand for FAA, EASA, ANAC across 737, A320, 787, A350, E2 families.
Full ergonomic retrofit. Cushion + lumbar + headrest. One pallet, one shift.
Bundled retrofit covering all three pressure zones. Designed to be installed during a single overnight C-check with two technicians per cabin. Pricing is per-seat-bundled (saves ~14% vs individual kits). Compatible with most narrowbody and widebody economy seats from Recaro CL3710, Collins Pinnacle, and Safran Z200 families.
Materials · Multi-density foam, ABS frame, aramid fire barriers, antimicrobial cover
Each kit is engineered to a single retrofit envelope: same attachment points, same flammability cert package, same crew changeover playbook.

Zoned-density seatpan cushion. -23% pressure points.
Replaces the existing seatpan foam with a multi-zone density cushion mapped to passenger anthropometry. Front rail uses softer 28kg/m3 foam to relieve thigh pressure; rear pelvic zone uses firmer 65kg/m3 for hip support. Same envelope as OEM cushion, no certification of seat structure required.
Adaptive memory-foam lumbar core. Drop-in. STC-ready.
Single-component lumbar insert that retrofits behind the existing seatback foam. Distributes pressure across the L3-L5 vertebrae using zoned visco-elastic foam. Installs in under 4 minutes per seat during routine C-checks. STC modular for 737NG / 737 MAX / A320 / A320neo families.
Wing-fold headrest with cervical support. Snap-on.
Headrest replacement with three-axis adjustable wings, integrated cervical bolster, and antimicrobial knit cover. Ships pre-mounted on OEM-compatible spine bracket. No tooling required to install during cabin turnaround.
Compatibility envelope locked to seat-rail pitch — not to OEM seat brand. If your fleet flies these airframes, our kits drop in.
