Deep Seating
Deep Seat Straight Modular Sectional Configuration: This 4 Seater straight configuration is 140 inches wide and includes arm and armless seaters—forming a clean linear deep-seat layout designed for adaptable living spaces. As part of a reconfigurable modular system, additional modules can be added over time to expand into larger sectional arrangements.
32D High-Density Structural Foam with 26" Deep Seating: Built with 32-density high-resilience foam across seats, arms, and backrests, the sectional delivers structured, supportive comfort designed to maintain shape and alignment through everyday use. The generous 26-inch seat depth provides relaxed lounge positioning while preserving balanced firmness without excessive sink-in softness.
Suede Finish Performance Upholstery (OEKO-TEX® Certified): Upholstered in refined suede finish performance fabric with a subtle sheen and soft hand feel, the material is OEKO-TEX® Standard 100 certified and compliant with California TB117-2013 standards. The finish combines durability with a clean, architectural aesthetic suited for everyday residential use.
Reinforced Internal Frame Construction with Anti-Skid Stability: Engineered with a durable internal frame and structured seat base, the system maintains stability across configurations. Each boneless module includes an integrated anti-skid base to help preserve alignment once positioned, supporting intuitive reconfiguration without compromising structural integrity.
Vacuum Compressed, No-Assembly Setup: Each frameless module is vacuum compressed for efficient delivery and easier handling. No tools or assembly are required—simply unpack and allow 24–72 hours for the foam to fully expand and regain its intended form. Minor dimensional variation of approximately ½–1 inch may occur due to compression and measurement tolerance.
Boneless Deep Seat Modular Sectional Sofa in a Box | Oak & Birch$849.99
A boneless modular sectional sofa that ships in a box and sets up in minutes — no frame, no assembly, just deep, sinking comfort. This cloud couch style sofa comes in 3-seater and 4-seater configurations, built from high-density foam and wrapped in durable upholstery that holds its shape without any internal structure.
Customized modules can be used as independent units.
Product Overview
The Oak & Birch Solene straight sectional is a fully modular, frameless sofa designed around a 32D high-density foam core. Available in a 3-seater (110"W) and 4-seater (140"W), it delivers a deep 36-inch seat profile built for genuine lounging — not perching.
The boneless construction eliminates metal frames, wood joints, and mechanical elements entirely. Each module connects flush to the next, creating a seamless sofa surface that maintains its shape through daily use. The suede finish performance fabric is OEKO-TEX® Standard 100 certified and meets California TB117-2013 flammability standards.
As part of the Solene modular system, straight sections can be combined with corner pieces, additional seats, or an ottoman to grow into an L-shaped or U-shaped layout over time — without replacing what you already own.
Each module ships vacuum compressed in individual boxes. No tools or assembly are required — unpack and allow 24–72 hours for full foam expansion. Minor dimensional variation of approximately ½–1 inch may occur due to compression tolerance.
