Plank Firm Luxe: Pressure relief test results

A deep indentation and a fast response time are typically indicators of good pressure relief

Our 25kg weight hardly sank into the Plank Firm Luxe, no matter where we put it on the bed. As a result, don't expect much cushioning; the Plank Luxe won't yield beneath you. If you want more of a 'hug' at the shoulder and hip, consider the Saatva Classic or the Helix Midnight Luxe. The same weight sank more than an inch deeper into these mattresses, demonstrating how the soft cushioning gives way beneath you.
