Square Rectangle DFS Cushions – Custom Foam Replacements Made to Fit

If your Square Rectangle DFS Cushions have gone saggy, flat, or lifeless, it’s time for a proper upgrade. Our made-to-measure foam replacements bring back the comfort, structure, and shape your sofa used to have — all without changing the covers or replacing the entire suite.

This square or rectangular shape is common in many DFS sofas, especially on the main seat units. But you’ll also find these cushions in SCS, Sofology, Furniture Village, Harveys, and more.


Foam Cushion Replacements for DFS Square or Rectangle Shapes

We custom cut every insert to fit your existing cover. Whether your Square Rectangle DFS Cushions were originally filled with feather, fibre, or soft foam, our replacements offer long-lasting support that actually holds its shape.

You can choose from three comfort levels:

  • Soft – relaxed feel with some give

  • Medium – best for everyday seating

  • Firm – supportive and resilient for high-use sofas

Add an optional fibre wrap to create a plumper, more rounded look — great if you’re switching from feather or want a softer edge.


What Sofas Use Square Rectangle DFS Cushions?

This shape turns up across a wide range of popular sofas — not just DFS. You’ll find similar seat cushion designs in:

  • SCS sofas with straight seat pads

  • Sofology ranges with clean lines and boxy proportions

  • Furniture Village and Harveys modular or fixed-back sofas

  • Next and M&S standard and scatter back sofas

  • And in modern styles from IKEA, Made.com, Habitat, and others

If your cushion has four straight sides and sharp corners, our Square Rectangle DFS Cushions are the perfect fit.
