The Problem
Support inserts for sofa cushions rescue sunken sofa cushions
Tired of sinking into a flat, worn-out sofa cushion every time you sit down? Over time, the foam in sofa cushions loses its resilience, resulting in an uncomfortable seat that neither supports your back nor feels fresh. This support insert solves it by being placed under the existing cushion – it instantly restores firmness without you needing to buy a new sofa or new cushions.
How it works
Done in four easy steps
The Material
40D high-density foam that holds its shape
The support insert is made of 40D high-density foam which distributes body weight evenly across the entire seat. Compared to a cushion that has already sunk in, the curved, ergonomic shape gives a visible lift instantly – the cushion is pushed upward instead of sinking downward with every sitting.
The Shape
Hidden edge that's invisible in the sofa
The tapered, curved edge is designed to hide within the cushion's padding – the sofa's appearance is not affected. The foam has high resilience, meaning it quickly regains its shape after being compressed, sitting after sitting.
