This ergonomic U-shaped swivel barrel chair features premium chenille channel tufted upholstery and foam-pocket spring cushion. Built with rubberwood base for 360° rotation, it has hidden storage and removable cushion for multi-scene home use. After opening the compression bag (Note: do not cut with a knife, so as not to damage the product), if there are wrinkles around the cushion corners, you need to wait for about 72 hours. It is recommended that you pat and knead the corners of the sofa to help the foam recover better.If you need any help, please take a picture and contact the seller.
