THINK, STURDY, HEAVY DUTY, DURABLE. Very sturdy. Easy installation guide. Easy installation: Less than 30 minutes. The bottom legs and top, cap-like cover of the poles were already pre-installed, making installation, a breeze. Just ensure the Spacers snaps into the grooves of the poles so as to hold it in place, following the arrow marks on them . When done properly, you should hear a click/snap sound, confirming it's in place. The Spacers have slim linear jaws. These should be lined up with the poles's grooves and push into place (unto the grooves so they sit in the grooves). You should hear a snap sound. If you're having difficulty, just snap one (“1”) Spacers into any groves. Then slide it up or down unto the intended groove. Its pairs though, should be snapped into the groove at the same position as the first one (prior to it). But to hear the snap sound, just position it at the intended groove (or 1/8” above the intended groove) while you lift its bottom up a little (maybe 45 degrees) at the same time, push snap it into place into the grove — press push it down into the groove, into position. It's like, a little up and down snap down in place in succession). When done, properly, you should hear the click/snap sound. Requirement: Two persons because it's quite heavy. But I managed on my own because, I didn't need to attached it to the wall (though that was the requirements (to keep it sturdy). I highly recommend.
