The size is a shame... even though there are cases that can be stored separately with a depth of up to 20cm, there is only a depth of 14cm, so there is a loss in storage under the bed. This time, I bought a new bed and all the other things I needed from NITORI, so I made the lower half of the bed into a drawer and the other half into storage under the bed, but the flooring is bare wood, so I can't store clothes or seasonal items there as they are, so I looked around for a case that would be just right for under the bed, but there wasn't one that was the right size. This case was good in terms of width and length, but it was only 14cm deep, so when you store something thick, you have to fold it up to save space, so it doesn't have as much storage capacity as you might think. It's a shame that if it was 6cm deeper, with a depth of 20cm, it would have had outstanding storage capacity. If the storage space under the bed could be up to 20cm deep, I would have liked to see that type in the lineup. I think it would be a shame to only have a size that matches the type with a low height under the bed, so I hope that a 20cm deep type will be added to the lineup in the future.
