Should Cushion Inserts Be Bigger Than Covers?

Yes, cushion inserts should generally be larger than the covers. For a luxuriously full look, choose an insert that is 5 cm larger than the cover for square cushions (e.g., a 55 x 55 cm insert for a 50 x 50 cm cover).

This ensures the corners are filled and the cushion looks properly plumped.

That's because, in commercial stores, there is no good "one-size-up" filling for rectangular covers.

At Mood & Pattern, we use slightly larger inserts for all our cushion covers (both square and rectangular), ensuring a perfect, plush fit.

What is the Most Comfortable Cushion Filling?

We recommend feather inserts for their optimal combination of firmness, weight, body, and long-lasting aesthetic appeal.

If allergies are a concern, there are high-quality synthetic alternatives available that replicate the softness of feather inserts.


Another aspect to consider is the amount of filling material (e.g., feathers) inside the pillow as it dictates both how the pillow looks and feels.

Too much filling can result in an overstuffed and overly firm pillow, while too little may lead to a saggy appearance with inadequate support. We find that pillows with medium firmness offer the most appealing look and feel.

For your convenience, our feather cushion inserts, carefully tested for fit and quality, are available for purchase with all our cushion covers.
