I've ordered many things online and am used to putting them together. I'm pretty mechanical, have all the right tools, etc. This lounge was a NIGHTMARE because the diagram was so pale and there were NO written directions! Finally got it together and was very disappointed to find that there is a crosspiece right where your tailbone is when you sit! Thank goodness we had already planned to use a cushion on it or I would have to send it back. 
This chaise is lovely and well made, but poorly designed and has terrible instructions. I ordered 2! The next one should be a breeze to put together, but the direction hassle is totally unnecessary. We chose it because we did not want arms.
