Questions about beds and mattresses answered. And some stories told.

If your mattress is too soft, adding a mattress topper usually won’t fix the problem—in fact, most toppers are designed to add cushioning, which would make it even softer.

Here’s a breakdown:

When a Topper Helps

• If your mattress is too firm and uncomfortable, a soft topper can improve pressure relief and comfort.

• If your mattress is in decent condition but feels uneven or slightly uncomfortable, a topper can add a slightly more consistent surface.

When a Topper Won’t Help

• If the mattress is too soft and lacking support, a topper won’t restore firmness—it can only add more softness or, at best, provide a thin layer of support.

• If the mattress is sagging, a topper will simply sink along with it and result in an even softer experience.

Better Solutions for a Too-Soft Mattress

• Use a firmer topper (like a latex or high-density foam topper), which can add a bit of support, though it won’t fully correct deep softness or indentations.

• Flip or rotate the mattress (if it’s double-sided) to even out wear.

• Add a bunkie board or plywood under the mattress to reduce sagging and make the feel a little firmer.

• Replace the mattress if it’s old or structurally failing.

In short: a topper can help if you choose a firm one and your mattress isn’t completely worn out. But if your mattress is saggy or far too soft, replacement is usually the best fix.
