Product upgrades. Goodnight Home's "LeSleep Era" series has launched three mattresses: LeSleep No. 1, LeSleep Vitality, and LeSleep Pure Sleep. They not only use GoodNight's patented technology for shoulder and waist protection mattresses, but also can meet the needs of users of different ages and stages. Due to different sleep comfort requirements, Goodnight Sleep No. 1 was removed from the shelves due to product upgrades and new replacement products.
