Thank you for viewing. This is a low-resilience cushion from the popular "True Sleeper" series. Since I have no opportunity to use it, I am selling it as a new, unused item. Product Features Ultimate comfort: The unique low-resilience material "Ultra Visco Elastic" disperses body pressure, making it less likely to cause your buttocks to hurt even after sitting for long periods. Reversible design: You can use it according to your preference. Clean to use: The cover is removable and washable, so you can always keep it clean.
