Hard to assemble
Color: Grey
This is extremely hard to put together, but once its together it is pretty good. You will need to secure it to something. It falls over.

Do not buy this protection plan!
Warning! The details of this Warranty are misleading and make you feel like they will pretty much replace anything. I am trying to have stained discolored cushions replaced on lounge chairs, less than six months old. Talking to a customer service representative is out of the question. They ask a few multiple-choice questions and base your claim on that. My claim was denied and that is the end of it. I have spent $80.99 on two different asurion protection plans need and now I feel like I have wasted $162.00. I'm not happy and will never buy this protection plan again. Now I have to find and purchase new cushions for replacement.
