Description
Lonstrand Topseal is Lonseal’s premium biophilic-inspired sheet vinyl flooring, designed to contribute to restorative responses such as reducing stress, improving cognitive function and creativity, and supporting overall well-being. Its design mimics the natural bark of a tree, creating a harmonious connection with the earth and offering a sense of healing and tranquility within any interior space.
