Poor design
Wood top arrived with some damage to the edge, leaving splinters, so that wasn’t the best start. It just highlighted that a cat jumping up, was going to damage the wood over time, which could potentially leave cat injured.
The cushion on top is held on by a few velcro strips only, not very secure at all. For both the damage and the poor design I requested to return the barrel for a refund, which was accepted. I have replaced with the Diogenes cat barrel which is a much better design.
