## Description

iMount EDF21S Electric Standing Desk/Ergonomic Height Adjustable Sit-Stand Workstation (Frame Only) Silver : desertcart.co.uk: Home & Kitchen

Review: Good quality for a decent price - Bought this in an attempt to turn my WfH space into a functional stand-up setup, but without breaking the bank on the £400-1.000 full stand-up desks. I considered the cheaper, crank operated ones, however I couldn't see myself bothered to lift and lower it 3-4 times a day, so this seemed the best compromise for price/functionality. It doesn't have the fancy memory buttons that raises it to predefined heights like the more expensive models do, but keeping a finger on the button for a few seconds vs. a single push is far from an effort. Besides, the space I have available is quite narrow and this was the only frame I could find shallow enough to fit it (less than 50cm deep to the wall). I kept the top from my existing IKEA Micke desk and installed on this electric frame + a set of new IKEA Alex drawers to replace/add more storage space - decent result. The legs are sturdy and the desk doesn't wobble on operation or when fully raised (which was my fear). Assembly takes about 1-2 hrs with the tools and instructions provided in the box. Setting it in its place is definitely a 2 people job though. The sticky cable ties that included are not great, but you'll need a proper tray to handle cable management anyway if a computer is meant to go on top of it. Got a £10 Signum that does the job in the same trip to IKEA back when they were open. I've seen someone suggesting a wobble cushion to stand on (feet/heels will hurt after a full day standing when you're not wearing any shoes) - I find it a meh solution. It helps with heel soreness and strengthening angle muscles, but annoying at times when I'm balancing on one foot in work meetings. Been using this setup together with an arm mount for a secondary screen and laptop since May 2020 and it's made a massive difference from the makeshift solution I had before (see photo). The stand-up frame has been working well so far and it changed the dynamic of WfH - I didn't even have this at the office.
Review: Excellent product - really happy - Fast delivery, secure/compact packaging and easy assembly. For me, product quality, sturdiness and height is most important (I'm 6'4" tall and this desk reaches a comfortable standing height for me). Of course, like most other products of this type, the desk is frame only so I also purchased an IKEA Linnmon white table top (100x60cm) from another seller which fits as though it were designed for the frame even though it's for an IKEA table! Along with a dual arm monitor clamp this provides ample desktop space for me to work If you position it correctly then the power cable will hardly be noticeable even at highest position. The motor action is smooth and fairly quick to raise/lower. I live in a small flat and I was a little concerned that the desk might look clunky or dominate my front room however I was pleasantly surprised about how good the product looks and it fits nicely into the corner of the room. Highly recommended.

## Questions & Answers

**Q: Is the framing white or silver?**
A: Hi, the frame is a gray colour, unfortunately the images we got from the manufacturer are not good. It is a fairly light gray and not a shiny silver colour.

**Q: Is this a dual motor desk frame ?**
A: No this is a single-motor frame. Please check Allcam EDF12D ( https://www.amazon.co.uk/dp/B075FWRG93 ) or EDF32D ( https://www.amazon.co.uk/dp/B08FBK3MCP ) for dual-motor desk frames which also have bigger height adjustment ranges.

**Q: Is it possible to mount wheels or casters for portability?**
A: Yes. Here is the compatible wheels: https://www.amazon.co.uk/dp/B08YJZDTNQ?ref=myi_title_dp

**Q: What guarantee comes with this desk?**
A: Standard 1 year but you do have to assemble yourself and add a table.
