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!

Great service and quick delivery

Just wanted to say how happy I am with my purchase from Red Chair Time. The blue Adirondack chair has been a perfect addition, as we were looking to add another chair to our patio. The whole ordering process was a breeze, and the owner provided great customer service. I was also beyond pleased with how this was packaged and arrived without a scratch. Thank you!

Quality Products and great service

Very happy with Red Chair Time. We ordered two Adirondack chairs and they arrived on time. When I emailed the company about shipping and tracking information they promptly responded and were able to provide me with the tracking number.
I appreciated the service, quality product and would order from Red Chair Time again.
