Works great but pricyNasrinIt’sa great , study and good looking but pricy4
Love this desk!GENEVIEVE L.I purchase this as I needed a sit-stand. I love it. I like the physical lever to go up and down. It is super solid with no wiggle evenat its highest. Very happy with my purchase. Note that it it quite heavy but I like that aspect.5
Good enoughZhenyuOverall, it’s a good product. A couple of potential improvements: 1. Sometimes lowering the table triggers a system reboot and a second attempt has to be made to make it work. 2. The control app should provide an API for smart home integration. I would love to have voice control of the table.4
Rock solid and adaptableMichelThis base is much more solid than any other Ikea option and better than many other 3rd party options. The same base fits all IDASEN tops (regardless of width/depth), and can easily be adapted to most other solid wood table tops making it very versatile. Not mentioned is that there is a Bluetooth app that can be used to remind you to swap from sitting to standing and automatically help you get it to the right heights after adjusting. Had to wait 3 months due to supply chain shortages, but it was 100% worth the wait. We now have 2 of these and have been using for over 5 years.5
Amazing product!CandaceVery convenient! The desk adjust perfectly for my 5 year old to complete his home work and crafts. The desk adjust to any comfortable level one desires. ⭐️ ⭐️ ⭐️ ⭐️ ⭐️.5
Nice investmentReginaI got this since I already had a table top to use. I was a bit working about the weight since the tabletop I had was 50lbs, but the motor on this can handle it no problem. Even with all my equipment on (triple monitor, monitor arm, laptop etc), it can still handle the weight.5
Modern design. Moves smoothly upMARIAModern design. Moves smoothly up and down. Ergonomically great.5
It's great! No complaints. IMylesIt's great! No complaints. I built it with a Lagkapten desktop and it's working well together!5
Great standing desk!GuilhermeGot this for my home office and it's the best desk I've had. Great value for money! - Super sturdy, doesn't wobble at all (jus a tiny side to side when fully extended). - Easy set up to control via bluetooth (mobile and desktop app available) and have preset heights. - Cable organizer net is perfect for keeping all the cables out of sight (even when in standing position).5
Idassen desk baseKIMIt was easy to assemble strong base great sit/stand desk5
You get what you pay forLukeThe base is very flimsy. I would be highly concerned if someone leaned up against the desk of it toppling over. There needs to be more support in the middle of the base, possibly a third leg or at the very least some more screws2


What is steel?

Steel has unique characteristics when it is stretched and shaped since it remains strong. It provides strength to everything from skyscrapers and cars to bed frames and outdoor furniture. The steel industry is moving in the direction of more energy-efficient production and stronger steel qualities. It doesn’t lose any of its properties when recycled and today steel is one of the most recycled materials in the world.
