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.

IP65 marine protection
Dust-resistant. Water-jet resistant. Built for demanding boat compartments.
The IP65-rated enclosure helps protect against dust, spray, and low-pressure water jets from any direction. It is suitable for many marine battery hatches and center-console installations, but it should not be submerged, pressure-washed, or installed where standing water can collect around the battery.

Let customers speak for us
from 6 reviewsJust 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!
Stacey is assisting me with the.purchase/delivery process very consistently to insure my full satisfaction. Hopefully I’ll get the registration in time when the weather gets warmer.
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.
This end table was just the right size for our small outdoor balcony to accompany the 2' plain bench chairs. Love it!! Shipping was quick and installation a breeze!
We purchased two of these chairs and received quick confirmation of the order along with quick shipping! Chairs look just as website promised! Love them!!
