I may have to return these chaise lounges...  While I have never had any trouble putting together other items with many more parts, these are quite difficult because, the holes are not in the right location, you have to pull the fabric away from the holes to be able to screw the legs, the key is not strong enough to do the work of screwing these big screws, fabric gets in the way of the screwing, the key finally gets stripped from all the work and has to be turned around!  I had to use plyers to help the key do its work and putting the two legs together took me about THREE HOURS! Aside from the openings being hard to reach, the holes are in the wrong places, the fabric gets in the way (even after cutting it out!), and the key is too feeble for the job!  What a disaster, may have to return!
