Multifunctional cushion

Abstract

This product consists of two cushions that are typically folded vertically for convenient storage. In this state, they can be used as pillows or chairs. The upper cushion can be tilted diagonally upwards and adjusted to the user's preferred angle, allowing it to be used as a backrest, maintaining posture. A trapezoidal tongue at the bottom provides stability and supports the tilted backrest cushion, preventing it from tipping over. When used as a backrest, the lower cushion can be unfolded forward to create a chair with an adjustable backrest angle. Furthermore, by detaching the unfolded lower cushion (which can be separated from the upper cushion with a zipper or other fastener) from the backrest, the cushion can be used separately as a cushion, cushion, and backrest, allowing for various other uses. The upper and lower cushions of this product are equipped with buttons to prevent the internal filling from shifting and to assist in bending the cushion to adjust the angle (there are four buttons, but the same function can be achieved with one or two). In addition, in order to make the present design as light and strong as possible, as is clear from the appearance, a special frame is used in which the outer frame inside the upper cushion is rectangular and the inner frame is trapezoidal.
