Monitor stand that stands up!
Color: White
This monitor stand is absolutely perfect. It gives back inches of desk space and provides additional storage with the shelves and 2 small drawers. Assembly was simple and the stand is sturdy and looks great. The profile is low enough that your monitors are not too high up from your laptop/keyboard. Definitely a game changes for the home office!

Great Monitor Riser/Stand!
Color: Oak, Color: Oak
I’m so happy with the way it turned out!! Easy assembly in about 15 min. It’s so cute and you can customize if you’d like the drawers to be on the left or right side. I just noticed a slight deviation in material dimensions so it looks a little off. But it’s still functional!

high quality and sturdy !
Color: Brown, Color: Brown
if you’re thinking about it, get it! i splurged to get this, but it’s so nice. it’s high quality and sturdy, plus it helps a lot to organize and keep things neat. putting it together was just like an ikea item and took much longer than i thought- around ~30-45 minutes, but it was worth it. i wanted a stand that would be able to fit my 2 monitors, and this is perfect. i’ve had it for over 6 months now and it still looks brand new! it really upgrades your desk space and makes it feel nicer. 10/10 recommend

Really like it
Color: Oak
Easy assembly and fits my desk. Looks nice and very happy with it. This sits on my motorized desk with two monitors on it. I was so happy with it, I purchased a 2nd one for my husbands desk.

Does Everything and More
Color: Oak
This stand allows me to raise my large monitor. It also gives me storage space for my sound bar, laptop, pillcase and more! I place my keyboard and mouse pad on the lowest portion of the stand when not in use. I like the two drawers on the side. I also like that there is room for a light and pencil case holder to the right of it. I had a real problem organizing my stuff on my desk but now I have a location for everything. I survived without it for so long, but now that I have the stand, I am really please with the set up. The only down side to having this with a large monitor is that it will block out a window completely. I had to buy a gaming light and install it from behind to give light to the front of the desk. Now my desk is fabulous. Great product but make sure that your desk is large enough to house this monitor riser as it is large. It does go on sale occasionally. So you can put a watch on the stand and purchase it when the price drops.
