Product Details

Description:

Experience the pinnacle of lounge luxury with our Frameless Cloud Lounge Sofa. Spanning an expansive 104 inches and engineered with a robust 1,200 lbs total weight capacity, this cloud-soft masterpiece is meticulously tailored to offer unmatched spatial freedom, ergonomic body-contouring support, and lasting architectural structure for your modern living space.

Key Features:

  • Cloud-Like Surround Comfort: Designed with generous proportions—featuring ultra-wide 15.7-inch armrests, a supportive 15.7-inch backrest, and an extra-deep 27.5-inch seat depth—that gently cradle your body from every angle, complemented by plush accent pillows for targeted lumbar relief.

  • Dual-Layer Comfort & 1,200 LBS High-Resilience Core: Upholstered in a buttery-soft, tailored plush knit fabric, the seating integrates a heavy-duty dual-layer core: cloud-soft surface plush paired with a high-density, high-resilience foam foundation. Capable of supporting up to 1,200 lbs, it maintains its pristine shape, exceptional stability, and bounce-back support over time.

  • Zero-Assembly, Effortless Setup: No tools, hardware, or complex manuals required. Simply unbox, allow the sofa to naturally expand to its full loft within 48 to 72 hours, and gently pat to restore its plush silhouette. (Shipped in two separate boxes for easy maneuvering).

  • Thoughtful, Low-Maintenance Details: Features removable, machine-washable pillow covers for effortless care, non-slip Hook-and-Loop fasteners between seating cushions and the base to prevent shifting, and a classic tufted construction that prevents fill displacement.

  • Versatile Modular Flexibility: Measuring 104" L x 43.3" W x 34.6" H, this versatile modular silhouette easily adapts, shifts, and reconfigures to suit any living room architecture or social setting, delivering robust safety and uncompromising comfort for the entire family.
