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

1
Remove the cushion
Lift the sunken seat cushion off the sofa or armchair.
2
Cut to size
Easily cut the foam sheet with regular scissors to the exact right size.
3
Place in the center
Place the support insert centered in the seat, under the existing padding.
4
Put the cushion back
Put the cushion back – done! The seat is instantly firmer.

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.

Vanliga frågor

Vilka mått har stödinlägget?

Stödinlägget mäter 50 × 50 cm och är 5 cm tjockt (20W x 20D x 2H tum).

Vad är stödinlägget gjort av?

Det är tillverkat av 40D högdensitetsskum i grå färg, format med en ergonomiskt välvd design.

Kan jag anpassa storleken?

Ja, skummet går enkelt att klippa till med en vanlig sax för att passa exakt din soffa, fåtölj eller stol.

Hur installerar jag stödinlägget?

Ta bort den sjunkna sittdynan, klipp skummet till rätt storlek om det behövs, placera det i mitten av sätet och lägg tillbaka dynan.

Syns stödinlägget när dynan ligger tillbaka?

Nej, den avsmalnande kanten är designad för att döljas i dynans stoppning och påverkar inte soffans utseende.
