The modular storage shelf set 2121x2 includes components for two storage (wall) cubes with some spare parts if you want to convert it into open shelving. This shelf is versatility at its finest. Create a stair­ like shelf, two W shelves, L­ shelves, cubes for the wall or the floor; no matter how you assemble the 2121, you will end up with a storage system that looks modern, fresh, yet simple and understated while giving you a myriad of storage options. It is perfect for your living room, your home office, the kitchen, or even the bathroom. Because of its fantastic durable ABS plastic finish, the cubes can even be placed within the shower.

We originally purchased the corner shelving, but later figured to create two separate units: a TV stand and a small corner display. The color is vibrant and they make a perfect addition to our place.

Very good design, best for DIYer

I have actually bought a few combination to make a display shelf for my store. I have installed LED strip light and custom made a few medium thickness clear and matt finish acrylic board to the shelf. The final outcome and price is very good, it's a great product if you are a DIY person. I will send a picture to expand furniture, see if they will post it out for demo because there are products of mine on the display already when I took the picture. I will definitely buy more combination later on when I "expand" my store.

I have a very limited space to house my amplifiers/speakers for my karaoke system. I searched everywhere, including online, for the right size and quality (the amps were small but sturdy and heavy), but there's just nothing out there. Until I stumbled upon a picture of one of Expand Furniture's modular shelving units on Google. I followed the link and bingo! Long story short, the guys there were very helpful, and accommodated my very customized sizes and shapes for the said project. I was just thankful their office is just in Vancouver (I live in Surrey), and not somewhere in Toronto or Nova Scotia, lol! Bottom line, product is of excellent quality, easy to assemble, and very flexible to suit in whatever space you have. I highly recommend it and would do business again with them in the future.
