Game-changer for me
Color: Light Grey
I’ve had a basement office for a while. I share a big room with my work bench. I’ve always just had a curtain hanging between the two, but after a promotion, I decided it was time for something more professional looking. This divider is awesome, and move-able when I need the space for my workbench activities.
The frame is very sturdy - impressively sturdy even. The felt walls are thick enough to take even heavy duty tacks.
There are three things that could make it even better, but none of them are enough to knock a star off my review, because this is truly a quality piece of office gear.
1. Put a magnetic strip on the top bars so that you could hang a little heavier items or add magnetic hooks. I plan to buy some magnetic tape to allow for this.
2. Allow the panels to be locked at the top. The locking wheels do a decent job of keeping everything in place, but if you could also lock the top of the frames, it would greatly increase stability. Note that it is already quite stable, but the top locks would make it very similar to actual cubicle walls.
3. Put a swivel caster on the middle wheel bars. This would allow you to configure the panels and the “feet” at angles other than 90 degrees when desired.
Again, these suggestions would take a fantastic item and put it into 6-star rarefied air. It is truly a great product as-is, but I would gladly pay another $100 for this item if it had these additional features.

Flimsy and cheap screws
Screws snapped off when I tried to drill htem in and no matter how I try to get the leg pieces in they will NOT stay. Falls apart, screws snap off, the middle axle holes arent even lined up so you cant install one of the pieces in the first place.

Easy to assemble. Works well. Looks nice.
Color: Light Grey, Color: Light Grey
Works for what we need. Easy to put together. Diagram provided was clear. One of the lil screws didn't fit perfectly, but it works well enough. Came with all the lil tools you need to assemble. Product frame is sturdy and hardware (seems heavy duty enough, metal and not plastic) all fits together very nicely. Would buy again if i need another one.
