Quick verdict: Buy the Rain Design mStand if you want a solid, single-piece aluminum platform that doubles as a heat sink, with a built-in cable hole and a space to tuck your keyboard away. Buy the Twelve South Curve if you prefer a lighter, open, sculpted look that keeps air moving under the laptop. Both raise the screen about 6 inches and neither adjusts, so this is a choice between two design philosophies rather than two different feature sets.

The Core Difference: Solid Platform vs Open Frame#
The mStand is made from a single piece of aluminum shaped into a solid platform. The laptop rests flat on top, and the metal is designed to draw heat away from the laptop's base and act as a heat sink. It is a substantial object that looks like it belongs to the laptop, and it has been a desk staple for years.
The Twelve South Curve takes a more open approach. It is a sculpted aluminum stand that cradles the laptop while leaving the underside exposed, so air can circulate freely around it. The result is a lighter visual footprint on the desk.
Both stands cool the laptop, but in different ways: the mStand conducts heat into its metal, while the Curve gets out of the way and lets air do the work.
Height and Ergonomics#
Rain Design lists a lift of 5.9 inches for the mStand, and Twelve South rates the Curve at 6 inches. In practice that difference is negligible — both raise the screen by roughly the same amount, bringing it closer to eye level and reducing the downward neck angle of working on a laptop flat on the desk.
Neither stand is adjustable. That is the shared trade-off of this design: you get rigid, wobble-free support and clean lines, but you cannot tune the height for your chair, desk, or body. If you need a specific height, look at an adjustable stand instead.
Both stands also assume you will use a separate keyboard and mouse. Once the laptop is raised, its built-in keyboard is at an awkward angle for long typing sessions.
Desk Space and Cable Management#
The mStand has two practical extras. A hole at the back routes your charging and accessory cables neatly behind the stand, and the open space underneath the platform lets you slide your keyboard away when you need the desk surface clear.
The Curve's design also leaves room for a keyboard in front of it, and its silicone pads protect the laptop's finish from scratches. It does not have a dedicated cable hole, so cables simply run behind it.
Fit and Portability#
Rain Design sizes the mStand mainly for MacBooks and laptops around 15 inches, so check your laptop's dimensions if it is larger. The Curve is designed with MacBooks in mind as well.
Neither is meant to travel. Both are solid aluminum stands built to stay on a desk, so if you need a stand for a laptop bag, a folding model is the better fit.
Who Should Buy Which#
Choose the Rain Design mStand if you:
- Want a solid platform that doubles as a heat sink
- Value a built-in cable hole for a tidy setup
- Like being able to tuck your keyboard under the stand
- Use a MacBook or a laptop around 15 inches
Choose the Twelve South Curve if you:
- Prefer an open, sculpted design with a lighter look on the desk
- Want air to flow freely under the laptop
- Like silicone pads protecting your laptop's finish
- Want a slightly higher 6-inch lift
Frequently Asked Questions#
Is the mStand or the Twelve South Curve better for cooling?#
Both help. The mStand's single-piece aluminum body acts as a heat sink and draws heat away from the laptop, while the Curve's open design lets air move freely underneath. Either is a clear improvement over a laptop sitting flat on a desk.
Are the mStand and Curve adjustable?#
No. Both are fixed-height stands, raising the screen by about 6 inches. If you need to set a specific height or angle, choose an adjustable laptop stand instead.
Do I need an external keyboard with a laptop stand?#
Yes, for comfortable long sessions. Raising the laptop brings the screen closer to eye level but puts its keyboard at an awkward angle, so pair either stand with a separate keyboard and mouse.
Which laptop stand is better for a MacBook?#
Both are designed with MacBooks in mind and match their aluminum finish. The mStand suits MacBooks and laptops around 15 inches, and the Curve is also built with MacBooks as its primary fit. Choose based on whether you want a solid platform or an open frame.
The Verdict#
The Rain Design mStand is the more practical pick, thanks to its heat-sink platform, cable hole, and keyboard stash space. The Twelve South Curve is the better choice if you want an open, sculpted design that lets air flow under your laptop and looks lighter on the desk. Both deliver the same core benefit — a screen raised about 6 inches — so pick the shape that suits your desk, and see our full laptop stand reviews for more options.
