My husband and I received a pair of GCI Packseats as a wedding gift, MORE THAN 17 YEARS AGO. We have used them and loved them, but they wore out. When recently cleaning out, I contemplated throwing them away (the seat portion was too frayed to reliably use), but when I noticed how well-made the stool was in general, I decided to see if GCI could sell me a replacement seat. When I called customer service, they immediately said they would replace both stools entirely because they are backed by a lifetime warranty. And so they did. I would buy anything from GCI - what a special company. The replacements were shipped promptly and are the same, if not better, quality. We are so happy with GCI; we look forward to another two decades plus using these Packstools. Thank you.
