About this cushion
Our Deep Seat Chair & Seatback Set is a matched pair of cushions — one seat, one back — built for the wide, deep-frame lounge chairs common to sectional and modular outdoor seating. Because the two pieces are sewn separately, they sit flush inside the frame without a fastener, and each carries its own boxed edge and hidden zipper for a clean, tailored fit.
The seat is built with high-density foam for a supportive bottom; the back is a soft blown poly-fiber bun — the same lounge-chair construction used on deep-seat sets like Birch Lane / Wayfair NC10146. Pick the size that matches your chair frame's footprint (both cushions are 5" thick), then choose your fabric and we'll cut and sew the set to order.
- Boxed edge with a hidden zipper on both the seat and back cushion, each with a removable cover
- Separate seat and back pieces sized to sit flush inside a deep-seat frame — no ties needed
- Foam seat + blown poly-fiber back
- Four deep-seat footprints: 23"×25", 24"×24", 25"×26", and 26"×30" (each cushion 5" thick)
- Made to order in your choice of performance outdoor fabric
