⭐⭐⭐⭐⭐ Sterilite makes the best plastic shelves. Assembles in 5 minutes with no tools, sturdy, and holds a lot. Some of mine have been holding audiobooks in my garage for well over a decade with no sagging! — K King⭐⭐⭐⭐⭐ I needed some shelving that I could put together without tools and could fit in a small space. This was perfect. I put it together in minutes. I bought a bigger shelf, same type, a little more cumbersome to assemble for one person. It was from a well known brand. Pieces were missing. I figured out a work around. I just wouldn’t put on the last shelf. I bought another one, missing pieces. This one had all the pieces, it’s very sturdy, holds a lot of weight and much less expensive than the well known brand. If you’re looking for a smaller shelf, consider this one. — Violet⭐⭐⭐⭐⭐ Package was delivered in great shape. Product seems pretty solid. Went together with ease. Nice size for my garage. Looking to purchase another. — Bill C

What Customers Say:

⭐⭐⭐⭐⭐ I love these shelves! I have lost count of how many I have. They're big, tough, chunky, and sturdy. Perfect for a storage room, garage shop, etc... Not hard to assemble, and well worth the price. — Mark Twain⭐⭐⭐⭐⭐ Shelves arrived before they were due in. Build was quick and easy. They are outside under a deck ready for farm harvesting duties, and as seen below, already serving as drying racks for the early garlic harvest. I thought these were well-priced, and the size was perfect (much more depth) than anything else I found. Hoping these stand up to both the weather (under a protective overhang) and the dirt over time. — GDK⭐⭐⭐⭐⭐ These storage shelves are great,super well made! Alot more sturdy and bigger than I thought! I bought 3 and they are perfect for my new shed! Very Happy with purchase fits alot of stuff!! — Mary gonzales

What Customers Say:

⭐⭐⭐⭐⭐ I bought this to store metals and other things on my back porch. This is perfect, it holds the weight perfectly with no problem. It took me a while to find a nice shelf to hold the amount of weight I needed to put on it. This shelf was it, actually I bought 2 of them and am very happy with the purchase. The shelves are nice and thick and very easy to put together. — Roxanne⭐⭐⭐⭐⭐ I love these shelves. They work perfectly. They are strong, lightweight and easy to put together. This two pack had small plastic binding pieces that holds the two units together next to each other. So they function as one unit. — Lisa J.⭐⭐⭐⭐⭐ Perfect fit and more sturdy than expected. But as sturdy as I hoped it would be. Holds all of my file boxes and important papers as well as the small totes. All of those important things you need to grab in an emergency. Just like I needed it to do and it gives everything ventilation. Live in a damp area and that's important around here. Not planning on using the top shelf for anything heavy so it's not necessary to connect it to the wall and it has the clips to do that if you want. — Becky E
