I really did not know what to expect from a laminated particle-board and PVC pipe wall-shelving unit. However, I needed to find something inexpensive, for a tiny and limited space that would help to organize some of my clutter, and in addition keep my items fully accessible.I am pleasantly surprised how well this unit looks when it’s all set up and assembled. It contains and stores all my manicure and pedicure products that were previously scattered in several different areas around my room, my closet and my bathroom. Furthermore, the unit is sturdy and it does not wobble with my regular normal usage, even though I have a lot weight on the top two levels.The assembly was fast and easy, it took me approximately 20 minutes to put the entire unit together on my own. No tools are necessary other than a scissors to open up the packages, and my own two hands to fit the storage rack together. The included assembly manual was easy to follow and has pictures for all the different parts, and shows how each piece connects to another.I love the way the shelves have all rounded ends, and without any sharp corners. Furthermore, although the fabric storage bins look small, they are actually very spacious, and each bin holds all the loose items that were in two of my overstuffed bathroom vanity drawers.General Description for the 4-Tier Unit W/Storage Bins:THE UNIT HEIGHT IS 43”, which keeps all my items on the top level at a convenient eye level (and for reference, I am a shorter person, at ‘almost’ 5’ 2”).Length: This unit measures 23 ¾” from one side to the other, therefore it will fit into a 24” length of space.Width: From the bottom baseboard, (in our home the baseboard protrudes a little bit from the wall) the unit measures 11 ¾” – from the backside and into the room.Space Between the Levels (Shelves): The amount of USABLE space between one shelf and other is a touch over 13” to about 13 ¼”. Therefore, any item that’s 13” will fit, but 13 ¼” just may scrape at the level for the next shelf up.Storage Bin area: I have my unit set up so that the storage bins are at the bottom with the included divider in the middle. However, this area offers some versatility.1. I could assemble this unit with the two shelves that connect the divider for either of the two areas above,OR2. Leave it out entirely, and just not have a divider at all.Storage Bin Measurements:Lengthwise: from side to side 9 ½”Width: from front to back 11”Depth: 11 ½” deep, therefore, I was able to empty an overfilled bathroom vanity drawer into each of the bins (one full drawer in each bin). In addition, these bins DO come with bottom inserts for a little extra strength and durability at the bottom.This 4-tier storage unit with bins has so many versatile uses, kitchen, pantry, playroom, bedroom, bathroom, closet and it would be ideal in a child’s room too. Although it fits in a very small area, and takes up very little space, it holds a lot of stuff. The shelves hold a substantial amount of weight, and although the storage bins look small, in reality they are spacious. This unit is solid, the shelves do NOT wobble, all the wood shelves and corners have rounded edges, and the entire unit remains securely upright. In addition, the unit looks very nice, and even though it is a contemporary piece, it should fit in and blend with most interior styles.
