【Sturdy Construction Ensures High Strength】Elevated on 4 solid wood legs, this fabric sofa features a robust engineered wood frame that ensures sturdy construction and a high weight capacity of up to 350 kg. 【Adjustable Sofa Back】The convertible sofa bed is constructed of 3-position seat-to-backrest angle adjustment. A 105-degree angle provides a slightly reclined position on a regular basis. A 140-degree reclining position might put the least stress on the spine. 180-degree flat lying makes occasional couch sleeping commodious. 【Easy-to-adjust】This click-clack sleeper sofa is of an easy backrest angle control design. You can use the simple mechanism to adjust it at 105, 140, and 180 degrees. Simply fold the backrest forward first to unlock the angle setting.
