A futon consists of fine natural fibers that are delicate and malleable. If creases or bulges have formed due to transport or storage, they can usually be smoothed out by evenly pressing them flat with the palm of your hand.
It is normal for a new futon not to match its nominal dimensions exactly at first. Initially, it may be 1 to 2 cm shorter or narrower, as well as slightly thicker. This is due to the fibers having loosened during manufacturing and transport; over time, they settle, and the futon reaches its final shape.
Depressions or slight indentations may form during the initial lay-in period. These are normal and vary in degree depending on the futon type, body weight, and the surface underneath. They generally even out over time and do not usually affect sleeping comfort.
The duration of the settling-in phase depends primarily on the ratio between the size of the futon and the user's body weight. A small futon used by a heavy person may reach its final shape after just a few weeks. With a large futon and a lighter person, this process can take one to two years. After that, the futon changes only slowly, becoming merely slightly flatter over the years.
Regular turning and rotating helps the futon maintain an even shape. During the initial lay-in period, a schedule of roughly every 2–3 weeks is recommended. Once the futon has reached its final shape, turning it about every three months is sufficient.
This settling-in phase is a completely normal part of futon care and affects almost every natural-fiber futon—whether it is made of cotton, coconut fiber, or latex.
