This has held up surprisingly well, through a house move and several trips up and down a spiral staircase (I’m indecisive).

We have one 17 lb cat and one 9lb cat, both are extremely aggressive climbers and I expect to replace this type of tree every six months or so. HOWEVER this tree looks practically new and the sisal rope has survived, we’ll see how long it stays. It’s been almost a year at this point, I think.
