Flip-up bed, semi-double, excellent breathability, shelf, outlet, thin standard bonnell coil mattress included, side opening, semi-double, large depth What I wanted was breathability and storage capacity. Point 1 Excellent breathability The floorboards are made of sturdy natural wood slats wrapped in soft fabric, a new type of material that has never been seen before. The fabric on the surface prevents dust from entering the storage area while ensuring breathability of the slats. Point 2 Large capacity storage The maximum storage capacity is 830 liters! You can store all your bulky luggage such as suitcases, electric fans, and futon vacuum cleaners. Point 3 There are 2 types of opening and closing You can choose between vertical and horizontal opening, so you can install it to suit the layout of your room. Point 4 With 2 outlets It comes with two outlets, so you can fully charge your smartphone or tablet, which are essential in our daily lives, while you sleep.
