@joshpuetz Hey Josh, as Fatima mentioned above, our testing showed that Spark supports over 100lbs on the upper level. But more important to most people than strength is stiffness - Spark doesn't wobble at all while you type or mouse.

@cchurch5 Quoting from their website: "Our testing showed that Spark successfully supports weights of over 100lbs on the upper level!" It looks like Spark will support monitors on the upper level - which Oristand cautions against.

@ksfatima Wow that's interesting. The one thing I wish the Oristand could do is support my computer monitor. I wonder if it can support a 27" iMac?

@cchurch5 @ksfatima Hey Chris - Great question! Spark does great with the 27" iMac!

@cchurch5 The biggest difference is that we opted for very stiff and robust over folds flat in a jiffy. Spark also provides a slight negative tilt on the keyboard tray, in keeping with the most current ergonomics: http://www.quittingsitting.com/d... .

@cchurch5 One more thing - Spark's keyboard tray is offset horizontally (flippable for lefties), to provide plenty of room for your mouse / trackpad, but still keep your keyboard lined up with your screen.

@maxwellhallel Hey Max, our beta testers indicated en masse that they much preferred a robust, lightweight solution that they could easily move in / out than a less robust folding option like some others. Spark is easy enough to disassemble / reassemble to be a great travel companion, but you likely won't want to break it down and build it up every day.

@maxwellhallel But to be clear, when disassembled, Spark folds flat into a tidy 18"x14"x3" package!

@novica93 Great question! Medium is now in stock and will ship within 2 business days (normally faster). Small and Large are expected to start shipping on 8/30, but may slide as late as 9/10.
