"I tend to be a klutz when it comes to assembling furniture like this, since 1) I never can think three-dimensionally the way the diagrams are shown in the instructions and 2) I'm clumsy with tools, never getting things in straight. I previously had very bad luck trying to assemble Top Fin furniture purchased at a competing B&M pet shop. There were so many parts to put together, but that was besides the problem. The materials were cheap and fragile. The nails wouldn't hammer in straight, causing the "wood" to crack. Some pieces didn't look like their illustration counterpart. And there seemed to be too many parts to keep track of what went where. After several frustrating hours, I sent it back the next day for refund.
Aquatic Fundamentals takes the guesswork out of all that, making it fairly intuitive with its short and simple digram and easy to keep track of parts. While all you need is a Phillips screwdriver to put the whole thing together, I recommend having some extra screws and perhaps pliers or a power tool as backup. I found the black screws to be rather "soft." It was pretty hard to screw in (I was doing it manually). Eventually, the screw stopped halfway and wouldn't go any further. The screwdriver wore out the top of the screw from the wear and tear, so I had to remove it with pliers and use a separate (i.e., not from this kit) set of screws. That worked just fine.
Although it is rather easy to assemble, I would recommend having a second person to help you keep everything perfectly aligned as you put in each piece. When you're done, you get a rather good, sturdy piece of furniture does your aquarium proud. It's very easy to move around once assembled, so you can decide where it will look best before you commit your tank to it.
Petco seems to have this on sale for around $95 on a semi-regular basis. That was what I paid for the inferior Top Fin stand. It's great deal for great product."
