If your Equal Sided Taper DFS Cushions have lost their shape, feel flat, or need constant fluffing, it’s time for a proper upgrade. Our custom-made foam cushion inserts are cut to match your original covers, giving you a firm, supportive sit that lasts.
You’ll often find this tapered shape — wider at the front, narrower at the back, with angled sides — on DFS corner sofas and modular units. Instead of buying a new sofa, you can replace the cushion interiors and restore the comfort in one simple step.
Rather than putting up with sagging or uneven cushions, swap them out for our equal sided taper foam replacements. We cut each insert to your exact measurements, so they slide into the cover and fill it out properly — no lumps, no shifting, no awkward gaps.
To help you get the feel just right, we offer:
Soft foam – perfect for a relaxed, sink-in feel
Medium – ideal for daily use with balanced comfort
Firm – long-lasting and supportive for a more structured sit
You can also add a fibre wrap, which softens the edges and gives a plumper, more rounded finish — especially helpful if you’re switching from feather or fibre.
Although DFS is the most common brand for this shape, many other high-street sofas use the same cushion style. These include:
SCS corner sofas with angled or wedge seats
Sofology modular sofas with deep seating
Furniture Village and Harveys corner units
Next, IKEA, and M&S with modern angular designs
And brands like Made.com, Habitat, and Dwell
If your cushion tapers from front to back with equal angled sides, there’s a good chance this is the right replacement shape. Still unsure? Just send us a quick photo — we’ll confirm it for you.
We don’t just cut foam — we make it fit right, feel right, and last. Here’s why customers come back to us:
