If you're Ikea-capable, then this product will not be a problem for you. The instructions are quite simple and intuitive so you can easily put 1 and 1 together based on the graphs provided.The set comprises of 8 pieces of plastic films, long rods, medium rods, and short rods. As you can see from my image, the long rods are used for the long sides (back and front) of the shoe rack. The medium rods, are used on the two sides (left and right) of the shoe rack. Using the long and medium rods, and placing them through the designated slots in the plastic films, you'll be able to create the different levels/tiers of this shoe rack. The short rods are used between the different levels/tiers when you're stacking them up.It is IMPORTANT that you pay attention to the corner pieces so that you are connecting the long and medium rods in the correct placement, and that you are able to stack them up into a 7 tier rack at the end (by using the shortest rods). Those corner piece needs to be placed so that the two openings on opposite ends are in a vertical direction, allowing the two short rods to connect the tiers together. I made a mistake on my first one so I had to reposition them.Once you've put together every tier (it will take some stretching and angle adjustment when you're putting them together, but nothing too strenuous), the whole rack will seamlessly come together. The final product is sturdy and does not rock back and forth when placed on flat surface. Each tier can easily fit 5 pairs of large shoes (due to the extra spacing on opening in both ends), and likely 6+ pairs for shoes slippers/toms/heels.A conservative and realistic estimate of the number of shoes you can place on this 7 tier rack, is anywhere between 35 to 42. You can probably place more than 42 if you're primarily storing slippers/toms/heels/childrens shoes.
