This month Twelve South launched a new accessory for the iMac, ‌iMac‌ Pro, and external displays, called the "Curve Riser." Similar to its HiRise products, the Curve Riser elevates your ‌iMac‌ to a position that's supposed to be more ergonomic for most users, while also providing some storage underneath the ‌iMac‌.

From a materials standpoint, the Curve Riser matches Twelve South's established standard as a premium accessory maker; it's built from a sleek metal and only comes in black. There's no front or back door, and although the accessory has a far bigger footprint than any ‌iMac‌ stand I've owned (coming in at 9 by 12 inches), its design is airy, sleek, and unobtrusive.

The idea behind ‌iMac‌ stands like the Curve Riser is that Apple's desktop computer (and most fixed-height computers) aren't naturally ergonomic. If you provide a little bit of height to your setup, ideally with the top of your display hitting your eye level, you can sit with a straight back and keep all of the display in your vision without any awkward neck tilts.

Twelve South's original (and now discontinued) HiRise for iMac was my first go-to ‌iMac‌ desk stand, and it provided a few different height levels, perfect for finding my favorite position. In recent years I transitioned to Satechi's Type-C Stand, which despite offering only one height option, provided a great selection of easily accessible front-facing ports.

The difference in height between Satechi's accessory and the Twelve South Curve Riser has been so drastic that I've barely gotten used to the Curve Riser over the past week, and I'm not sure that I should. The Satechi stand sits about 1.63 inches tall, which isn't a lot, but ultimately provided me with just the right eye level for my ‌iMac‌.

At 4.2 inches tall, the Curve Riser is simply too tall for me. I frequently have to tilt my head up and down when I work and move to different parts of the ‌iMac‌ display, with my eyes hitting just about the middle of the display when sitting tall. I have an adjustable desk, so there is some wiggle room to knock my ‌iMac‌ down lower, but not much.

This height will work for some users who are taller than me, but the inability to truly customize the exact height of the accessory is a let down at this $79.99 price point. Although Satechi's Type-C Stand is also a fixed height, it feels far more universal at just over an inch off the desktop and could easily hit the ergonomic sweet spot of more individuals than the Curve Riser.

The same goes for Twelve South's previous HiRise device, and the current HiRise Pro, which offers adjustable shelving heights at a far higher price of $169.99.

I've also seen concern over ‌iMac‌ stability when using a stand like this, but I've never had such issues or been worried about my ‌iMac‌ toppling over with any ‌iMac‌ stand, the Curve Riser included. The accessory has such a large footprint at twelve inches wide that there's plenty of space for the ‌iMac‌ base to sit atop the stand.

Given the weight of the ‌iMac‌ and the wide footprint of the Curve Riser, everything feels nice and sturdy once it's set up. Even in spaces of frequent traffic surrounding a desk, I couldn't really see anyone needing to worry about the ‌iMac‌ toppling off of the Curve Riser.

The new Curve Riser is also built to match the aesthetics of Twelve South's Curve and Curve SE for the MacBook, another ergonomically-minded accessory that lifts your Apple notebook into the air by about 6 inches.

The Curve for MacBook and Curve Riser

Another benefit of the Curve Riser is the desktop organization it offers with its small shelf, which measures 10 inches wide, 9.6 inches deep, and about 1.75 inches tall. This capacity can hold a Mac mini, various USB hubs, hard drives, your wallet, and more.

The shelf is certainly wide enough to hold quite a few items, making it a helpful tool to get a few pieces of clutter off of your desk. Still, the benefits of having a slight organization system don't quite outweigh the loss of adjustable height, which will hinder the accessory's usefulness for the majority of people.

The Curve Riser is available on Twelve South's website for $79.99.

$80...for that? There are better solutions to be found at lower prices.

Except, of course, raising your monitor is incredibly un-ergonomic. Ergonomics say to have the monitor lower so you're looking down into it. Tilting your head back at all is one of the worst positions you can be in while sitting and working for long periods.

No actual ergonomic expert would claim this is more ergonomic. It's actually much worse for you, in almost every situation.

no way. if you have kids or pets (cats) and your iMac is not against the wall, it's in danger already. i actually manufactured clamps to secure it to the desk. placing the computer on top of a thin metal construction is just asking for trouble.

A hardback book is a cheaper solution. I use a Windows book about 4" thick.
