Deep Seat Sofa Cushion Set — Seat & Back, Custom Size

Deep lounge sofas need both a seat and a back cushion working together, and when one flattens the whole seat feels off. Buying a matching seat and back set that fits a deep frame is nearly impossible off the shelf, since stores size for standard depth.

USCUSHION makes your deep seat sofa cushion set as a matched pair, cut to the exact depth, width, and height of your frame. You choose the foam density so the seat stays supportive at full depth, and one fabric across both pieces so the set looks consistent. Enter your measurements, pick your options, and the set arrives ready to drop in.

Why customers choose us:

• Matched seat and back: Seat and back cushions are made together so the fabric, thickness, and finish stay consistent across the set.
• Built for deep frames: Cut to the full seat depth of a lounge sofa so you are not perched on the front edge.
• Choose your foam density: Pick the firmness that keeps a deep seat supportive instead of swallowing you in.
• Any size to the inch: We match non-standard deep sofa dimensions that stores never carry.
• Removable zip covers: YKK zipper covers come off for machine washing so the set stays fresh through daily use.

• Cozy family movie nights, providing ample seating and comfort.
• Hosting gatherings with friends, where everyone can lounge comfortably.
• Creating a relaxing reading nook in a spacious living area.
• Transforming a casual living room into an inviting space for entertaining guests.
• Setting up a stylish yet comfortable space in a home office for breaks.
• Enhancing a modern aesthetic in a minimalist designed home.

This deep cushion sofa pairs well with accent chairs, ottomans, and coffee tables that complement its plush design. Ideal for use in living rooms, family rooms, or lounge areas, it works harmoniously with contemporary, transitional, or eclectic furniture styles.

Designer's Pick: For a deep cushion sofa, consider rich navy blue or charcoal gray to add sophistication while effectively hiding stains.
