What thickness BEDSTORY SPINEALIGN® mattress topper is best for back discomfort?

Go with 3 inches. It gives you the best mix of support and cushioning for most people with back pain.

Yes. It stops your mattress from sinking too much, which keeps your spine in a better position and eases lower back discomfort.

2 inch — a small firmness boost, for mattresses that are only a little too soft

3 inch — the most popular pick, good support and comfort together

4 inch — the most cushioning, best for older or very worn mattresses

Yes. Four straps grip the corners of your mattress, so the topper stays in place even when you raise or lower the bed.

Sometimes. If your mattress is still solid but has lost its comfort, this topper can fix that for less money. If your mattress sags or is broken down, you need a new mattress instead.

Yes. It shapes to your body while still holding you up, which keeps your spine straighter and takes pressure off your shoulders and hips.

It's firm, not soft or medium. It's made to stop sinking and add support. If your mattress is too firm and you want it softer, this isn't the right topper for that.

Unzip the cover and machine wash it like normal bedding. Never wash or dry the foam itself — just wipe it with a damp cloth if it needs cleaning, and let it air dry.

No. It's CertiPUR-US® and OEKO-TEX® certified, so it contains no fiberglass, formaldehyde, heavy metals, or harmful flame retardants.
