How much do you think a sturdy steel frame with reasonably precise synchronized lifting motors with a combined capacity of over 300lbs designed to put up with years of use and abuse should cost?
- simplekoala 13y agoWhat is a reasonable guess here..hmmm. I have no idea about how much these motors would cost but I am assuming given the number of office chairs (which move up and down with a lever) we produce, they shouldn't be costing a lot. We get good office chairs which support up to 300 lbs for under $100. I am assuming the technology for moving tables should be similarly priced. A sturdy steel frame + planks (wood/composite) + up/down motor/hydraulic lift shouldn't cost more than $300 in my subjective opinion. I am not willing to pay more than that. Wonder how much would IKEA charge for these, if they made one (edited for typos).
- jlgreco 13y agoOne problem I see with the chair-piston approach is that if you don't get each leg moving up or down at the same rate then you might get a jam. This could probably be overcome if it is indeed an issue at all, but probably worth considering.
- simplekoala 13y agoI have a simple(minded) idea here. Connect a damn horizontal rod between the two pistons/moving-legs on each side
- nknighthb 13y agoWhich will cause the desk to jam at a (potentially disastrous) angle when the motors get out of sync. Are you a programmer? Do you like it when a non-programmer tells you "just do X", because it must obviously be so simple? Why, then, are you so sure that you can come up with a better design than mechanical engineers without even studying the problem?
- simplekoala 13y agoApologies for shooting from the hip. Never meant to say I can come up with a better design than mechanical engineers. You seem to suggest that building this table requires some serious engineering chops. May be there is some truth to it. As a layman ( in mechanical engineering ) I find it extremely hard to believe that technology for synchronized hydraulic lifts is not commoditized yet. It just feels like these ergonomic goods producing companies are selling chairs/tables with super high markups ($900-$1500) for ergo chairs - really?). Seems like you have a better handle on the production costs of a hight-adjustable table. How much does it really cost?
- nicholassmith 13y agoThey probably make about 20-30% profit on each one dependent on the company. Making shit is expensive unless you're doing it at scale, the majority of people don't care about adjustable desks so the marketshare is by nature a niche. You then have staffing costs, design costs, distribution costs.
- kyzyl 13y agoFWIW, we certainly can make synchronized tandem lifts, but as always it comes down to costs. Basically if you want both actuators to move in unison, you either need to directly link them mechanically, which is expensive to build/repair, and not very feasible over large distances, or you need to connect them electrically via their control signals. In the latter case, you would usually synchronize their controller clocks, and specify the motors/cylinders/whatever to both have a very tight positioning tolerance. Then you mount the surface being moved on a system of bearings that have enough freedom s.t. it will self center automatically, absorbing the tiny bit of misalignment that can (and WILL) occur. However, in my experience it's almost always better to use two passive, i.e. non-lifting, supports along with one actuator in the middle that is twice as powerful. In heavy lift applications it often comes down to getting a single cylinder that is powerful enough without blowing the cost through the roof. Nevertheless, if you look at marine architecture, airport gangways, earth moving machinery etc. you will often see just a single lifting point. And in three paragraphs we've gone from office chair pistons to front-end loaders! Yay HN! As I said... for what it's worth ;-)
- jlgreco 13y agoI think if you want to do it cheap, then a handcrank, 4 rubber belt drives, and 4 screw legs would be the way to go. The problem would be making it look acceptable (either hide the mechanism, or display it prominently and make it look nice.
- DigitalJack 13y agopackage that with a corded drill and you are good to go.
- ygra 13y agoThey do make one. They charge 600 €.
- nknighthb 13y agoThe >300lbs on a GeekDesk Max isn't how much it can support, it's how much it can lift. Your office chair can't lift 300lbs. It can't lift much at all. I also don't believe in the ability of a pair of $300 hydraulic lifts to consistently reproduce my presets. As someone who weighs close to 300lbs, I can also tell you you won't find a good office chair rated for 300lbs for under $100. Go look at the specs on office chairs closely. Most of them will be rated for less than 250lbs with no more than a few hours/day of use. If you want your own crappy top (planks? really?), the actual cost of a GeekDesk Max is $725-745. The non-max (275lbs lifting capacity) is $525-549. You want a vastly inferior product to save $225?
- minor_nitwit 13y agoWhy does a desk need to lift 300 lbs? Seems like a ridiculous requirement.
- nknighthb 13y ago50lbs desk surface, 3x ~15lbs LCDs, 5.6lbs laptop, ~15lbs desktop, other electronics, lamps, some books, papers, stands, containers with misc parts and things, whatever else I might be working on. It's a 6.5' x 2.6' foot surface, it holds a lot more than a laptop.
- michaelbuddy 13y agoI got a geek desk, the original. Put my own top of plywood on it finished. I've got 3 24" flatscreens and abunch of other crap. I'm still not even near the lifting capacity. But I think of the higher end desk as a good idea for a quieter motor, not so much the need for more weight. With that said, I think a hand crank desk should be fine for most of us. If only I could find one that's reasonably cheaper. The hand crank desks I've seen basically cost the same as the geekdesk though, which I don't understand at all.
- BrandonMarc 13y agoPerhaps because you weigh 160 lbs and your spouse / sexetary weighs 140 lbs?
- encoderer 13y agoHydraulic lifts on chairs work because you can stand up to raise the chair! It doesn't have to lift hardly any weight.
- jamwt 13y agoA bit pedantic, but I think you mean "pneumatic lifts". Unless you have something very exotic, there's no fluid in your chair!
- StavrosK 13y ago$150.
- baddox 13y agoPerhaps, but a cheap and sturdy plain old IKEA desk with a wooden desktop costs about that much.
- simplekoala 13y agoWhy should it be made of wood? Any composite material will do. We just need to build one which is affordable. It looks like a niche product right now, and a whole lot of average americans cannot afford to purchase one. It looks like one of those things we have to pay a premium to own. You get sturdy and durable hydraulic barber chairs between $100-$150. A table with the same kind of lift mechanism should cost you ~$750 to own?
- vacri 13y agoYou get sturdy and durable hydraulic barber chairs between $100-$150. This is difficult to believe, given that new cheap office/task chairs start at that price. Do you have a link?
- jlgreco 13y agoThese are the sort that I see in most barber shops, and are in that price-range: http://www.bestmassagesalon.com/product_p/pro3.htm http://www.bestmassagesalon.com/product_p/pro3.htm They probably wouldn't make a good drop-in replacement for office chairs since they aren't on wheels. On the other hand, footrests are nice...
- jlgreco 13y ago"Why should it be made of wood? Any composite material will do." To be clear, the IKEA table is probably made of a composite wood, not a proper slab of wood, but I agree with your point. Material cost should not dominate the price of a desk. To be honest though, I think the value of a motorized desk is being overblown. I have just put my desk up on 4 stacks of office paper in the past; worked great. Everyone needs new expensive toys though...
- shelf 13y agoI'm gonna go with US $120-305 per piece. http://www.alibaba.com/product-gs/311870898/T_feet_electric_adjustable_desk.html http://www.alibaba.com/product-gs/311870898/T_feet_electric_... Probably best to leave out the garish tabletop and find your own, though.
- rossjudson 13y agoAlibaba gives unexpected insights into the products all around us!
- gneissguise 13y agoHas anyone ordered anything like this from alibaba? Just wondering if it was legit.
- nknighthb 13y agoThen surely you'll be importing them en masse and selling for $400 a pop to undercut GeekDesk et al., yes?
- vl 13y agoWell, it's all good, but buy one for this price first. Even when Ikea was selling motorized desks, they weren't this cheap.
- bane 13y agoDunno, but fixed height desks of similar style and excellent build quality run around $150. http://www.ikea.com/us/en/catalog/products/S89806740/#/S19806753 http://www.ikea.com/us/en/catalog/products/S89806740/#/S1980...
- nknighthb 13y agoThat table has 40% the surface area of my desk, and a static weight limit of 176lbs. I'd have to buy two for $300, still wouldn't have the same surface area, then I'd have to put it on something else because its maximum height is 32 inches (mine's over 43 when I'm standing). And, of course, the non-adjustability is a complete deal-breaker. Over 5 years, a $1000 desk is about $0.55/day. It's strange to me how many people think it's outrageous for such a critical tool to cost that much.
- BrandonMarc 13y agoOver 5 years, a $1000 desk is about $0.55/day. It's strange to me how many people think it's outrageous for such a critical tool to cost that much. I suspect they're thinking about how a $100 desk is 1/10 that price, whether it's amortized over 5 years or not.
