Ergonomic Lumbar Support Seat Cushion Set
Back & Tailbone Pain
Ergonomic Lumbar Support Seat Cushion Set
One cushion for your back, one for your seat — support that meets you at both ends of sitting.
- Fills the gap at your lower back so you stop slouching without trying.
- Cradles your hips and tailbone so pressure never builds up underneath you.
- Two pieces, strapped and non-slip, that stay exactly where you put them.
- Breathable covers on both pieces so neither ever traps heat.
Description
The Ergonomic Lumbar Support Seat Cushion Set pairs a contoured lumbar cushion with a U-shaped seat cushion, so your lower back and your hips get supported together instead of just one or the other. The lumbar piece straps to your chair's backrest and fills the natural gap at the small of your back, while the seat cushion cradles your hips and tailbone to keep pressure from building up underneath you.
Supportive foam cores and breathable mesh covers on both pieces stay comfortable through long hours of sitting.
Ideal for: desk chairs, home offices, and everyday seating.
Material: supportive foam core with breathable mesh covers on each piece.

Designed around your back and your seat, together
-
1
Lumbar curve
The backrest cushion fills the natural gap at the small of your back that most chairs leave empty.
-
2
Tailbone & hips
The seat cushion's U-shaped cut-out lifts pressure off your tailbone and cradles both hips evenly.
-
3
Upper back & posture
With your lower back and seat both supported, your spine naturally stacks straighter instead of rounding.
-
4
Thighs & circulation
The seat cushion's tapered front edge keeps pressure off the backs of your thighs, so circulation stays easy.
