What Customers Say
Real Logs. Real Reactions.
"The two logs that we purchased are in our Nature Play Garden. I know the kids love using them!"
Cathleen M.
Nature Play Garden
"We're quite happy with our log :) It's been very well loved by a bunch of preschoolers here in Philly. It's been living exclusively outdoors in our garden space on astroturf."
Jake C.
Preschool Garden — Philadelphia, PA
"The Hollow Log Tube sculptures are holding up perfectly and are still on loan at the Center of Science and Industry in Columbus. I've been tremendously happy with their results."
Deric G.

"Thank you. Product looks great!"

"The kids love the small hollowed logs and the sanded stumps. Thanks!"
Erin C.
Verified Customer
"The log has aged wonderfully! We did sand the interior and outer flat edges before we used it to prevent splinters, and now the bottom half has smoothed out from use and natural oils of people using the tunnel. We're seeing the outer bark layer separate just a bit from the core, but nothing major. Overall, we (and our guests) are super happy with the purchase, and it has definitely been a drawing feature for many families."

"The log is currently in a sensory garden at a K-4 school. I think it has held up pretty well, considering that we had an issue with the kids pulling off the bark."
Dionne L.
Sensory Garden — K-4 School
"It's holding up well. 4½ years in Montana's heat and cold and only a little bit of wood rot. It's a part of the yard in my daycare so someone's always standing on it, jumping off it, etc. Very well made!"
Michael D.
Daycare — Montana
"Our one big log and tree cookies are holding up well in the Outdoor Play Oasis. The big hollow log has lost a fair amount of its bark."
Deb W.
Outdoor Play Oasis
"The tunnel was a lovely addition to our recognized nature school here in Miami, FL, and it gave all it could and now we need another one."
Maite M.
Nature School — Miami, FL
"Your product is the best thing I have found in a long while. I love these logs — my huge log was a big hit with my dog, all kids think it's just the best, and my cat tunnels are a big hit with the cats. Everyone loves how it looks with hollow tubes running through all the walls."
Robert C.
Residential — Beehives, Dogs & Cats
"This is how we used the tree trunk — as a hiding place, sliding and rope climbing. Tree bark has gone, still looks good. We love it."
