The Dark medical mattress is a durable and hygienic model with increased firmness, ideal for those who value solid support. Independent pocket springs ensure proper spi- nal alignment, while the double coir mat provides better ventilation and limits the buildup of moisture and mold. It is an excellent choice for individuals suffering from scolio- sis, discopathy, or sciatica, who are looking for a healthy, comfortable, and restorative rest.
