New, unused True Sleeper low-rebound cushion purchased from Shop Japan. Size: 450mm (length) x 450mm (width) x 150mm (height) Material: Cover: 100% polyester / Body: Urethane foam Retail price: 9,100 yen ---Introduction page from My Best Site--- The True Sleeper low-rebound cushion is recommended for those who prefer a soft, squishy feel. When actually used, it has a clinging fit, and it gives the impression that your buttocks won't get sore easily. Monitors also said, "The height and size are just right" and "It's comfortable even when sitting cross-legged." Another good point is that it doesn't trap heat easily, despite being made of urethane. The temperature increase after placing an electric warmer was about 14°C, which is better than the overall average of just under 16°C. It can be said that it is reasonably easy to use even in the hot season. The cover can be washed by putting it in a net, which is also a merit. The filling cannot be washed, but you can keep it clean by regularly taking care of the cover. The price is 9,100 yen including tax (refer to the official website) at the time of writing. It's on the higher side among the products tested this time, but the enveloping softness and comfort are points you can't miss. If you are looking for a soft cushion, please consider it.
