Why We Call It Red Chair Time ❤️ - Click to Read
Up north at the lake, life was simple—fishing, boating, bike rides, and sun-soaked afternoons. But the heart of it all was my mother, who loved nothing more than relaxing on the patio in her Tall Red Shellback Adirondack Chairs, surrounded by family and friends.

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.

Thank you for visiting!
