The "would-be" chaise sat upside down on the floor for a week, refusing to allow the final bolt to tighten on the back panel. After removing all and starting over from the top, not the bottom, we started getting somewhere. As for the legs, they finally required use of a power tool to fully tighten up. At this point we were 10 days into the project. Thank God I then had something to cradle my limp form as I finally collapsed in comfy relief, delighted with the outcome!

Pros: Worth the trouble
Cons: First: Call in the Handyman
