Why Does the Sofa Start to Sink in the Same Place?

Over time, it is common to notice that the sofa starts to sink in the same place, particularly in the area used most often at home. Before deciding that the upholstery has completely lost its structure, check how the cushions are arranged and whether the support underneath them is still adequate. A few simple measures can spread wear more evenly and extend the furniture’s lifespan.

Why does the sofa start to sink in the same spot?

When someone sits in the same place every day, that section is subjected to more weight and pressure. Over time, the foam, fibres or other upholstery materials may develop uneven compression.

The issue may also be connected to the structure beneath the cushions. Springs, webbing straps or other support systems can wear down, making one part sit lower than the rest of the sofa.

Can rotating the cushions help prevent uneven wear?

For sofas with removable, interchangeable cushions, changing their positions may distribute use more evenly. A cushion that always remains in the most-used spot can become more compressed than the others.

When the cushion shape allows it, it is worth swapping their positions from time to time. You may also turn them over or rotate them, but only where the manufacturer states that both sides are designed for use in this way.

Do sofa cushions need plumping?

Yes, if the sofa design permits it. Cushions in which filling has become compressed in one area can regain some of their shape when moved and rearranged regularly.

This should be done gently, without hitting the cushions or pulling the fabric excessively. Light rearranging helps spread the filling and prevents one area from remaining under constant pressure.

How can you tell whether the sofa support is the problem?

If an area remains sunken even after the cushions have been rearranged, inspect what happens when they are removed. Visible deformation in the structure underneath may show that the problem is not limited to the upholstery.

It is also important to check for displaced springs, loose webbing straps, broken parts or unusual noises. In these situations, simply plumping the cushion will not address the cause of the wear.
