It has a powder-coated steel frame that makes it very sturdy and durable. Thanks to the fitted curtains with hook and loop fasteners, you can easily close all four sides to create an enclosed area. The closed mesh is perfect for keeping flying insects out and giving you a private retreat. The swing bench can be converted into a cosy and comfortable bed for an even more relaxing experience. Two rectangular pillows and two cylindrical pillows are included for added comfort. Our bench needs to assemble.
