Size: 45*31*10cm. It not only allows you to sit comfortably, but also acts as a lumbar/foot cushion/pillow. Double O-shaped hollow design, the hips become more rounded as you sit, wrapped in a ring, and the legs are naturally brought together to tighten the flesh on both sides. V-shaped design, supporting the pelvis, sitting upright, and slowly becoming an S-shaped figure. The elasticity fits the support, and the pressure is naturally gone. The more you sit on the hips, the more sexy you are. Looking at your back, there will be a feeling of rising hormones. The short plush fabric on the front is light and comfortable, suitable for cold seasons; the bird's eye fabric on the back is breathable and heat-dissipating, suitable for hot seasons. The design of round holes on both sides solves the problem of sedentary ventilation. Strong stretch performance, convenient to fold both sides for storage when the cushion is not practical. The filling is made of memory foam particles, which relieves pressure and is not easy to deform.
