I made a purchase from Dinos online shopping and upon opening it, I realized I had bought the wrong size, so I put it away immediately. It is unused. This is a firm futon. It's not fluffy, and based on reviews, it seems to be highly rated by people whose backs hurt from sinking into the futon, but individual experiences may vary, so please make your own judgment. The reviews can be found on Dinos online shopping under the "Magic Futon" series. It's a 3cm thick futon with excellent breathability, lightweight and easy to handle, and can be folded into three for storage. - Thickness: 3cm - 100 x 205cm - Filling: 2.45kg - Materials: Outer fabric...
