Three Drawers Kitchen Cart (3 Colors)

I bought this cart about 4 years ago and it has held up pretty well. The top is still in great condition and the cabinet looks great. I use it as a craft cart and it has no problem holding all the supplies. The adjustable shelf is bowing a bit, but to be expected with the weight it is holding. One thing that is not awesome is over time, the screws have loosened, or something is causing it to not be square and it wobbles back and forth if pushed. I don’t move it around often, but if you want it to be a bit more mobile, I suggest regular tightening of screws.

Wondering if the 54" width measurement includes the spice and towel racks, and if those could be left off? My space is 42" wide. Thanks.
