The design of these is terrible. You can see the fittings from the sides. I have tried contacting Wayfair but so far they have not responded

The end pieces don’t sit flush on the shelves there too small! Soon as you put the screws in to fix the sides on the wood starts to chip off, they don’t have proper fixtures to fit them onto walls. These are very poorly made!

End pieces were too short and didn’t fit onto the end, meaning When on the wall you could even see the crew going into the wall and was not flush. Requested a refund and was accepted

The shelves don’t sit flush to the wall. Poor quality and ill fitting

Good shelves for moderate weighted items. Easy to assemble & used for a number of books, plants, etc. Regarding a few negative comments about these from others, there is a step of about 5-6mm between the base & the sides but this is to facilitate space for the hanging fixtures attached to the end panels. It is barely noticeable when the shelves are hung. The colour is a very dark grey. Don't expect a mid or silver grey, they are dark! Finally expect to supply your own screws & rawl plugs to hang the shelves. Screws should be 3.5 or 4mm diameter with countersunk heads.
