5. Distributes body pressure to reduce the burden on your body. The soft memory foam cushion is designed to be extremely soft and hard to reduce the burden of sitting posture. Reduces the thickness of the urethane on the tailbone and sciatica, and the three-dimensional seat is aligned with the roundness of the buttock, and disperses body pressure on the pelvis and buttocks. Reduces fatigue and provides a comfortable sitting experience
4. Front and back support design to help you stand your pelvis and guide you to a beautiful posture. The unique support shape supports your pelvis from the front and back, prevents your butt from shifting in front of your back. Simply sit down and guide your butt to the proper sitting position, and guide your pelvis into a beautiful posture
3. The KURA SEAT W seat has a gentle curved structure that matches the roundness of your buttocks. The seat surface of the seat has a smooth curved surface that matches the roundness of your hips. Unlike a flat seat, it fits around your hips from the front and back, so you can experience a gentle sitting experience
2. The position of the rider is noted: The rider who is riding maintains a beautiful posture, even on an unstable horse, and the back muscles have been pinned, and the upper body is stabilized. The secret was in the "saddle" of the horse. Saddle supports from the front and back to keep your butt from shifting in the middle of the seat. The KURA series was developed with a hint of the shape of this saddle
1. Supports comfortable desk work from your posture. In order to make it comfortable for long periods of time such as desk work, we use a low-resilient urethane foam that is gentle to sit on. Reduces pressure on your buttocks, and the unique shape of the horse saddle, supports a beautiful posture. The simple design and colors can be placed on top of the office chair to fit a variety of work situations
