Purchased several for both my husband and daughter. They love the shoeboxes! It was easy to assemble and only took about 7-10 min to put all these together with 3 people. Once you complete one you’ll be a pro.The front piece (which includes a swing door) and the back plate are the hard plastic pieces. The body of the shoeboxes are a flexible/flimsy plastic that can be shaped somewhat. So just know that in case you’re someone wanting hard pieces all the way around.The shoeboxes are pretty sturdy and easy to stack. Husband has a 6x5 set up and they have held up nicely— there is no worry that it will fall over while removing/inserting shoes.Husband is able to fit his size 11 sneakers (including bulkier Jordan’s and Air Max) comfortably. You could possibly fit a size 12 but I can’t imagine you can go bigger than that.Overall I would recommend this product.We actually just order more because they’re so more convenient and we’ve gotten more shoesEasy to assemble pretty sturdy and if it’s my shoes standing upright so exactly what I was looking for.These were easy to assemble and surprisingly sturdy. It is easy to find what you want since they are clear. They allow you to easily store a lot of shoes.I had read many reviews for all the shoe organizers on Amazon. Although other sellers had a similar looking item at a lower price, most of the reviews I read for this one was positive. One of the reviews had a video from a purchaser showing how to assemble it easier with very helpful tips (better than the video provided from the manufacturer). Mainly, put the "door end" on first, that way you can open the door to put your hand in it to then attach the bottom, making sure that the tabs that stick up for stacking are both facing up before attaching. Assembling them with your hand on the inside to line it up with the frame is WAY EASIER! I also felt confident in this seller as I had previously purchased a Jewelry Armoire that I am very happy with! :)I like them and will be buying again if they bring them back. I hope they do anyways. As far as sturdiness goes, I won’t be putting my heavier shoes in the upper containers. Those will only go in the bottom. For my sandals, crocs, and slides and any other lightweight shoes the upper ones will be fine. Assembly was easier than I thought it would be. All you have to do is take the tabs fold them inward punch out the little holes that are pre-cut and there is a little slot for the edge of the plastic box to go into. Once the box is completely in the front and back piece you will hear the tab click into place. I didn’t find it difficult at all. Overall I like these, they are so much easier than the plastic shoe boxes that have a lid. I can put two pairs of slides in each box which I love. Please bring these back!Its Definitely a lil difficult but once you find Nd read the quick 3 step directions u will have it together quick just food the tabs in Nd push till it clicks into place. Fits size 12 High Nd lowtop upright can prob fit a 13 sideways I’d buy again don’t get discouraged by the feel when setting up definitely sturdier then it looks when together Id stack them 10-15 high with no worriesRead the reviews before purchase! I knew I was purchasing a flimsy shell because of the reviews. That being said, they do stack nicely and fit most of my size 10 sneakers perfectly. I have one pair that has a very thick midsole that I have to tilt sideways in them, but the rest sit without a problem.OK, so after 30min of losing my mind, I figured out how to put these together.First, DONT use the instructions, they are nonsense. Don't rip anything off, and don't do what you _think_ you should based on looking at it.1. Fold the end sticking out tabs INWARDS so they would go towards the middle of the box2. slowly slip one side of the white ends over one of the folded down tabs, until you hear it click3. repeat - it will take some time to make all the edges go into the grooves in the ends, but the tabs folding inwards and clicking was the key to discovering how they work!These boxes are super easy to put together and stack. Loved these so much I immediately ordered anther set. It is such a space saver.BTW I have size 11 woman's or 9.5 men's sneakers. If you have tall heels 4inches or more you have to lay the shoes sideways to fit in.Love these! Excellent purchase. I am so happy with these organizers. My shoes are organized, easy to see and choose which to wear, and they are protected from dust or getting squashed by other pairs. I used the entire top part of my closet.PROS:- Easy to assemble- Clear faces to see shoes easily- Doors open and shut with ease- Stack perfectly on top of one another- Measurements provided were exact and fit right the T in the space I measured forThis style of organizer does take up space. However ...they can stack up real high if you are using wall space, and it is SO worth it to have shoes all in their own boxes in a visible way that you can easily get to. Looks better than most organizers i've tried and seen as well. I would prefer to down size if I needed to make these work in my space.I highly recommend!Actually used these for housing baby geckos. The assembly was a little frustrating/tedious but overall it wasn’t that difficult. They are very cheaply made but once you put them together they are sturdy enough. A little pricey in my opinion for the quality but will probably buy more because they get the job done and look good too.
