No Assembly Required - No assembly is required for the lounge sofa, and as the cushions are vacuum-compressed, allow up to 72 hours for them to return to their original shape. To expedite this process, you may knead the cushions gently, similar to a massage, to facilitate air circulation through the foam. This will enhance the cushions' rebound and help them become fluffy. If there are any wrinkles, use an iron to gently smooth them out. [Comfort Meets Practicality]:Crafted with high-density pure sponge padding , the sofa offers balanced softness and firmness for optimal comfort and body support. Five included throw pillows add versatile coziness for any occasion. After receiving the product, gently tap the sofa and pillow to accelerate the overall rebou.
