This modular deep seat sofa features luxurious cushions and high back pillows with sponge and premium cotton filling for superior resilience and softness. The modern design includes a cascading hem and detailed stitching. The modular system allows flexible combinations: add sections to convert into 2-seat, 3-seat, or 4-seat sofas; with ottomans, it can become L-shaped, U-shaped, sofa bed, or home theater configurations. Removable, washable covers and breathable, soft-touch corduroy fabric make maintenance easy. The thick cushion is made of 100% high-density foam (no built-in springs). High back and side pillows provide a warm hug design. Built with a sturdy wood frame supporting 300 lbs per seat. Assembly takes less than ten minutes with included instructions. Note: Cushions are vacuum-packed; allow at least 48 hours to fully expand.
