Please contact me before purchasing! The second image shows the basic style. The images 2, 3, and 4 show the full type. These are just for reference, as they only show the third row section. The dimensions between the frames are approximately 34 cm on the top gate side, 42 cm to the center ceiling, 46 cm in the center, and 27 cm at the bottom. It will be slightly narrower if you include the top board. (Please comment before purchasing.) [Specifications] The total length is about 190 cm (including the second row), and the total width is 120 cm, allowing adults to sleep comfortably. The lower part is 27 cm, so you can store luggage. The upper part is about 90 cm in length and about 116 cm in width. [Frame] Aluminum frame is used. [Cushion] The cushion material is 2 cm thick. You can sleep on it as is, or take it out and sit on it. We have chosen a moderate thickness! It is made of memory foam, so it won't leave marks. [Leather] The surface is made of water-resistant, lightweight, and durable PVC soft leather, which can be easily wiped clean if it gets dirty. [Back] We have selected a vinyl chloride sheet. It has an embossed finish for non-slip properties, elasticity, and flame resistance, making it resistant to fire and useful for camping! Also, it is selectable, with five types: white, gray, black, brown, and a checkered steel plate-style PVC sheet (silver only). The checkered steel plate style requires an additional fee. Also, considering that it would be difficult to get in and out if the entire space was converted into a bed, it is set up at the second position from the front of the second row seat. ※This is handmade. ※This is not a professional product, so the packaging will be simple. ※Some scratches may occur during work. ※A hex wrench is required. ※The second level does not include cushion material.
