I was looking for storage units to create a pantry but everything I found was not the right size or if it was, the shelves were not adjustable. I found this unit and I loved the amount of weight each shelf held but I wanted the shelves to be closer together and I needed 8-10 shelves total. I searched all over the web to see if I can get extra shelves for this unit but didn't find any, so I decided to get 2 units and use whatever shelves I needed for one unit. I figured that most likely I would've paid more than $50 for 3-5 extra shelves, so for $100 I ended up making one awesome pantry. I used just 8 shelves and stored away 2 shelves and remaining poles. (NOTE: each leg is made out of 2 poles that gets screwed on top of each other so you can actually create 2 shorter units out of one unit)The unit is pretty sturdy but it's a pain in the but to put together by one person. The shelves are held up in place by some plastic pieces that you have to connect and snap together in each corner and then lower the shelf from above on these pieces. The plastic pieces are marked with an arrow and the word TOP. Each pole has markings/indentations 1 inch apart all the way down. You hold 2 plastic piece together and place them around a pole, arrows pointing up, holding them together ABOVE the line on the pole where you want the shelf to end up. Holding the 2 pieces together and by sliding them down they end up in the indention on the pole at the level you want them to be. When they end up on the indention you'll hear a click and that's how you'll know they are locked together in the right place. Count to see on which indention you are on that pole and place the other pieces at the same level on the other 3 poles. Now, 2 things you have to know about these plastic pieces:1. They would not close together fully, meaning you might see a bit of a space between them.2. They stay put but when you lower the shelf you will have to hold each one in place and guide each corner of shelf's hole over them because if you don't do that and you hit one of pieces with the shelf they would snap open and you'll have to remove the shelf and connect the piece that disconnected from the pole. It would've been better if the plastic pieces were open only in one side and closing fully when snapped together. What I ended up doing was placing a piece of tape on one side of the plastic pieces (making one side like a door hinge) which made it easier for me to put the shelves over them. If I was hitting one corner by mistake the pieces would not snap off and fall down completely but stay on the pole giving me a chance to close them pretty quickly without having to remove the shelf anymore. At first I put tape all the way around the pieces but the tape was adding thickness to the pieces and they wouldn't fit in the shelves' holes. So, I tried tape only on one side and that worked. After all shelf's corners are places over the pieces, you will have to push down on the shelf, at the same time on all 4 corners to lock the shelf in place evenly.So, with all that said, the units are pretty nice. The plastic pieces need some design improvement. If they were designed better this unit would've been a breeze to put together.One thing I have to mention. I had room for a 46" or 48" W unit but that size unit was too deep for my space (I needed 12"-14"D unit and the 48"W they sell on Amazon is 18"-20"D). So I ended up buy this 36" W unit even though I was not using 10-12 inches of my space where I was planning to place the pantry. I made plans how to arrange baskets on each shelf based on the listed measurements. A lot of planning went into this since I had to consider how many baskets I needed and how much that would cost, finding the right size baskets etc, etc. Only after I ensemble the entire unit I found out that the 3 baskets I initially wanted to place side by side on each shelf would not fit and I was baffled not knowing why that would be.... Well, the unit is 36" W, meaning the shelves are 36" W but because the ploles are designed to be part of the shelves they take up about 3" of the shelf. From one pole to the other you have 33" width and because of that I couldn't use the baskets I needed to use and had to rethink the entire pantry, cost, sizes of items etc. Because of this unforeseen issue I lost a bit of space in the spot where I placed the unit (keep in mind that I could've used a much wider shelving unit to begin with) and I'm bumped about not using the space to the max as initially intended. I wish I knew about these details about the measurements before I made my decision to purchase this unit. The measurements were a very important part of my decision to purchase these units and they were not an easy item to ensemble and dissemble to send back to Amazon. Although my pantry turn up nice, I had a lot of headaches rearrange everything just because of the unknown measurements.After founding out that the shelves were not as wide as I expected them to be, I couldn't find baskets to fit so I ended up using Flat Rate shipping boxes from USPS (which are free, you can order them online or pick them up at a local USPS location) that I had to cut to size and covered in shelf/drawer lining. Not fun at all :(I would recommend this unit for it's sturdiness and price but buyer beware: you will have to spend some time putting it together if you don't have a 2nd person to help you. And, I hope you read my review if you're planning to use the the unit in a specific way where the exact measurements are a must to know before hand.I finished my pantry by covering the back and sides with a stiff plastic shower curtain, and with a fabric shower curtain for the front part.Another thing I need to mention is that if you need to slide something on the shelf back and forth (like I wanted, a box to be pulled out and put back) the shelf's front is a bit higher and the item on the shelf will sit a bit lower and the edge will have a bit of a "lip" so you'll have to lift the item up a little at the edge to get the item over the "lip". I didn't like that, so in order to make the shelf smooth front to back, I came up with the idea to put cardboard on the shelf but a bit smaller than the shelf so the thickness of the cardboard when sitting on the shelf away from "lip" will come up at the same height with the lip, thus making the shelf same level from front to back. I needed 8 cardboard pieces long enough and very inexpensive. I bought 2 moving boxes 18"x18"x16" from Menards ( about $5 with tax for both) and cut them lengthwise in 8 pieces. They were the perfect fit. To make sure the cardboard didn't move when pulling my boxes out, I taped the cardboard in each corner from underneath. Problem solved and it came out nice. I hope all this info might help someone who wants to use this unit for a pantry.Pictures:1. How the unit looks with the cardboard on each shelf2. Work in progress, how the flat rate boxes look after I cut them to the size I needed to be3. How the unit looks from the back with the plastic shower curtain covering the back and sides4. How everything looks and how the unit looks like with 8 shelves on it5. I ended up finding some baskets that were perfect fit and blended well with the flat rate boxes. I didn't like the baskets' colors much but I had no choice, I made them work :)6. How the flat rate boxes looked like after covering them in shelf/drawer lining I got at Dollar Tree store and label them too :) Also, on the shelf with the 2 green baskets, in the back of the shelf I used a lazy susan I had before to be able to easily access my tomato paste cans.7. Final product. Front covered with fabric shower curtain that's easy to pull up to one side (see picture #4 to see how it seats on left upper corner). On top of the unit I places 3 foldable rectangular boxes (from Menards $6 ea) that I'll use for very light items (toilet paper, paper towels, napkins etc). To make sure all weight is distributed ok and unit stays in place first I made sure feet were leveled properly (the unit had screws at the bottom of each foot so you screw and unscrew each feet to level it properly to an uneven floor). Second, I secured the unit with velcro and plastic cable ties to the railing thats on the back of the unit (the unit comes with ties to secure it to walls but I used my own ties)Third, I placed my heavy items on the lower shelves (cans, sugar, flour, oil etc). And lastly, I placed my light items (mixed in with some light weight ones) on the upper shelves and the top one.8. I needed more light so I found this light that has a magnet on the bottom and a hook to hang anywhere. I can move it on any shelf, (standing up, sideways, etc) and have my hands free when I pull out a box/basket etc. It's awesome. I know, too much info, sorry :)
