My fiance bought one of these a while back when COVID started, I was a little jealous! Now that I am going back to school and am spending more time using my computer I decided to cave and get one! I use it for my laptop and a dual monitor, so at first without an additional keyboard it was a little awkward but now that I have that it is SOOOO helpful. We use stability balls to help with back pain, support, and fidgeting but now I can stand up when I need to! They fit so nicely on our 2 person desk side by side (we got matching colors). It says it will hold up to 15 lbs, but that is on the lighter side, it holds my laptop, dual monitor and my 12lb cat when he decides to join and it doesn’t budge! The movement up and down takes a little bit of muscle work which is probably why it can hold up my cat! The best part about it, it comes put together completely, so no construction work! I really like it a lot!
