Retail price: ¥6490 (tax included), 25% OFF!! Price reduced. Brand: relax heal Features: Washable Color: Black Size: 45 x 45 x 6cm Material: Gel memory foam Shape: Trapezoid 【Size】Large size 45 x 45 x 6cm x extra thick type 【Please be aware of the seat height】Because it is extra thick at 6cm, the seat will be slightly higher when placed on a chair. Please consider that the seat height will increase by 3-4cm, depending on your weight. 【High-quality gel cushion】A gel cushion that incorporates all the evolutionary elements from conventional gel cushions: "extra thick," "TPE material," "large size," "new non-slip," and "popular black type." 【Extra thick 6cm x large size】The thickest 6cm gel cushion is now available in a large size. We have realized the most requested "extra thick type in extra-large size." A double-structured honeycomb gel cushion that doesn't get stuffy. 【Latest TPE material】A material with properties between plastic and rubber. It provides a seat that is not too soft and firmly supports the pelvis and lower back. A cushion that allows you to sit for a long time without your buttocks hurting. Due to its thickness, it may feel softer than a regular gel cushion. 【New non-slip】With large, sturdy non-slip particles, the non-slip function is significantly improved. It maintains the correct posture and is the optimal new non-slip type for a chair cushion. 【Black cushion】Can be used stylishly even without the cover. You can use it without the cover if you want to enjoy the feel of the gel material directly. 【Washable】Cleanliness is important because it is used on chairs every day. It comes with a washable cover, so you can always use it clean. ※Note: Because the cover is black, there is a possibility of color transfer due to the usage environment or the user's sweat. If you are concerned, please wash it separately once and try it on a chair before use. Especially for leather products, please be very careful as they are prone to color transfer.
