A constant humidity level of between 40 and 60% and a temperature of between 18 and 23 degrees Celsius are optimal for people and plants. If the humidity is extremely high or too low, solid wood furniture can warp; this may lead to open glue joints or cracks. We recommend you install a hygrometer and a thermometer in the room to monitor the humidity levels. If the humidity is extremely high or low, solid wood furniture may become deformed, it can either swell or shrink. When this happens, the wood expands and gets larger or contracts and gets smaller. The humidity can be improved with very simple means. Plants or water containers placed in the room often have a positive effect.
