Wool felt is a material made of pure wool and has many advantages. First of all, wool felt has good thermal insulation properties, which can effectively keep you warm. Secondly, wool felt has good moisture absorption and breathability, which can help regulate humidity and keep the indoor air fresh. In addition, wool felt is anti-bacterial, anti-mite and anti-static, helping to provide a healthy sleeping environment. In contrast, wool pads may not be as warm and moisture-absorbing and breathable as wool felt. Therefore, all things considered, wool felt is better.
