  • Publication number: 20150001900
    Abstract: A storage stool provided includes a stool stand and a stool lid. The stool stand includes a bottom face and a side wall extending upward along the bottom face edge. The bottom face and the side wall together form a storage chamber with an upper end having an opening. The side wall includes an inner face layer, an outer surface layer and an interlayer clamped between the former two. The interlayer has at least one layer made of a rigid material. The bottom of the stool stand is detachably connected to a rotary base. With a paperboard as the interlayer of the side wall, the storage stool is greatly improved in bearing capacity and safer in use. With the rotary base at the bottom, the stool stand can rotate 360°, so users can change direction without adjusting their sitting posture. The use is very convenient.
