Question: Does this have to rest on the wall? My washer has open space behind it (no wall) & I'm afraid it won't work because of that.
Document: Took some manipulating but I got it to work behind both my dryer and washer (I bought 2). Had to pull both from the wall and push down/move around the cords that sit behind the washer, but now I have extra storage space and tops of my washer and dryer are no longer cluttered.
I was able to fit all on my laundry detergents, dryer sheets, etc, and it is holding the weight of it all fantastically.This has been really useful for me and I'm probably going to purchase another one to go behind the washer so I can store my husbands protein and other work out supplements that I struggle to find the room for! Highly recommended!
I'm a short person and can't reach the laundry shelves on the wall way above my washer and dryer. I thought these would be perfect, but boy was I wrong. I have a white toploader washer and front loader dryer, both whirlpools. The shelves didn't fit because the top of the washer and dryer both slope up and back, and the shelves drooped toward the wall, the brackets never touching (even after moving them forward and backward). Nice idea but it doesn't work well in this instance.
I actually needed a bottom shelf for an old used refrigerator that I bought that didn't have a bottom shelf or crisper. I was able to combine this with an under bookshelf rack and use the braces that came with this as well to jerry-rig some extra shelf space at the bottom of this old refrigerator. I'm very happy with it for this use. It's sturdy and would also seem to work well for it's intended use as well, but I can't comment on how well it attaches to a washer.
My new washer and dryer are further from the wall than my old ones for some reason so this helps keep things from getting lost behind them. Of course mine are not level but these still work just fine. Sooner or later I will order another for the washer.
Unless you have the same type of washer, the same distance from the wall, with the same chair rail (that you can screw into) running behind the washer/dryer, this will not work if you plan to put items of very much weight on it. The support bracket is very flimsy. It cost more to &#34;return-ship&#34; than it is worth so I will just junk it.
This rack does not work if there is not a wall/structure behind it (like in the picture). My washer and dryer are both in the middle of a room ( because of where the drains and plugs are). Unfortunately the rack does not work if it doesn't have support behind it like in the picture. I can only sit light things on it such as dryer sheets. If I put a bottle of detergent on it, it sags back and the bottle eventually falls off.
This worked great over our dryer since the huge tube coming out the back kept it away from the wall. However there is not enough clearance behind the washer for this. Our kitchen has the washer/dryer facing each other. This might work well for people with side by sides so that they are lined up with the depth of the dryer. On another note, I put about 50 pounds of weight on it and it didn't budge.
Shelves came quickly and work great. Gives me the opportunity to use space that was useless and now things can't fall behind the washer or dryer!
When I saw this shelf I thought it was a great idea for used space. I am really happy I got it. It dosn't quite fit my dryer and I had to rest it a little againt the wall for the shelf to stay up. I still gave it 5 stars because it does the job well. I Enjoy having my laundry stuff right at hand.
Answer: Nope.  It does not have to lean against a wall.  I've found out that if you plan on over-loading the shelf, it helps!
