Smart Design 2-Tier Under Sink Expandable Organizer w/ 6 Adjustable Shelves - Expands 18 to 31 Inch - Solid Plastic Frame - for Sinks, Bathroom, Pantry, & Shelf Organization - Kitchen [Gray]

Easy assembly - no tools necessary. Shelves are adjustable vertically.If you have the space, there are 2 nubs on top of each frame for stacking one unit onto another. The frame (2) and panels (12) are heavy duty plastic. The crossbars (4) are metal. The panels are about 4" x 11.75" and snap onto the crossbars. I'm using it in a storage cabinet at the smallest width (17.75") and only 4 panels per tier can be snapped in (I have 4 panels left over). It is sturdy in this configuration. I would buy again!

I have a wardrobe (specifically an Ikea Brimnes wardrobe), and the bigger area measure 29.5” wide. But all the shoe racks I could find that looked like they would work for my needs were either 24” or 31”. Plus, I have some longer items hanging up, so I really needed a shoe rack that was closer to around 27”. But I also had boots in addition to shoes. That’s where this came in handy! Because not only can it be adjusted width-wise to the width I need, but the shelves are also adjustable up and down to help accommodate boots and shoes of different heights. So right now I have my boots on the bottom, and then the top two shelves are closer to each other up at the top, so I can fit two rows of short shoes (like sandals/slides, running shoes, Converse, etc.). There really wasn’t that much to it, so it was very easy to set up as well. The only flaw I found was that there was a tiny piece of plastic maybe a half an inch long that had almost chipped off (still attached but barely) on the edge of one of the side panels, but I just popped it back into place as best I could. It was just a tiny cosmetic flaw, and I honestly couldn’t care less about it (it’s a shoe rack...being used inside a wardrobe...that is behind closed doors nearly all the time...so it’s fine).Anyway, I would recommend if you’re looking for a two-tier shelf that’s very adjustable both height and width-wise.

Maybe it was just me but getting this thing installed under my sink was NOT an easy task. After nearly an hour, some swearing, and personal ingenuity I finally got the thing installed. Once in, it’s great. Holds all kinds of toiletries and is very sturdy.

Pretty good for under cabinet storage in bathroom. Made of plastic so wouldn’t be putting anything really heavy on it. But holds quite a bit, and can be reconfigured in many ways. Great for working around drain pipe.

I've had this several months now and while it does hold stuff, it has started to sag in the middle and I don't have both shelves full, nor do they have much heavy stuff on them. Kinda disappointing, since it looks like it would be sturdier/longer lasting.

I bought 6 of these for under sink storage and have loved them. Easy to assemble, perfect size for under sink storage and super pull out drawer feature! Price point was a bit steep in my opinion. We have thoroughly enjoyed all of them!

I've got two of these. One under the kitchen sink and one under the bathroom sink. Storage is seriously lacking in my one bedroom shotgun but these shelves help me optimize the space in my cabinets. I'm considering more for the other bottom cabinets in my kitchen. Super easy to put together and I love the versatility of the small shelf pieces so you can work around the plumbing.

This was a perfect way to organize my cabinet under the sink. I can actually find and access whatever I need.
