Deep Seat Chair & Seatback Set

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 Cushions only — furniture not included.
