Padding vs. suspension systems for tech

The hook

Foam padding cushions a hit. Suspension holds the device away from the walls, so less of a hit or a squeeze reaches it. How a laptop gets cracked in a bag is in laptop sleeves.

What is it

Simple foam padding lines a sleeve or compartment. It absorbs a direct hit, and it protects only where it is thick and present. Suspension goes further. It lifts the device off the contact surfaces with stretched material (like a trampoline) and absorbs energy in several directions. In a suspension sleeve, the device doesn't touch the walls under sideways load.

Why it matters

Foam works from the side it covers. A thick pad under the sleeve cushions a set-down, and padded walls cushion a squeeze. A thin spot in the foam is a spot with no protection. Suspension helps where the foam is thin or the compartment is packed tight, and it adds weight and cost. For a fragile or costly device that trade can be worth it. For a tablet it is more than you need.

How to spot it

Squeeze the padding between thumb and finger. Dense EVA foam or neoprene pushes back and springs back, while soft polyfoam crushes flat with little effort. The pinch test for all four sides is in laptop sleeves. Put your device in and tilt the bag side to side. If you feel it slide and knock against the walls, the protection is thin. For a suspension sleeve, shake the bag gently. The device should stay centered and feel supported from all sides. For padding in a camera setup, see camera, and for where padding sits on the straps and back, see padding placement.

When you don't need it

For tablets, e-readers or other light devices, where weight savings outweigh protection, simple padding suffices. So does a separate hardshell case. High-end suspension adds weight and cost, and it pays only for a fragile, high-value device.
