Why We Call It Red Chair Time ❤️ - Click to Read
When she lost her battle with cancer in 2023, I started Red Chair Time to honor her and help others still fighting. Those chairs symbolized comfort, connection, and peace—and now, every piece we sell carries that spirit forward.
This isn’t just about selling and living the lake life. It's about a life with purpose. A portion of every purchase supports cancer research, because our mission is personal. We’re here to create beautiful spaces—and to fund hope.
