A mattress pad is a quilted, cushioned layer that adds a little comfort and protects the mattress from everyday wear. A mattress protector is a thin barrier, usually waterproof, that guards against spills, sweat and allergens but adds almost no comfort. Many people use both.
Shoppers often use the words interchangeably, and some listings call a pad a "mattress cover" or a protector a "pad". The product description is the thing to read: padding and quilting means a pad, a waterproof backing means a protector.
If you want the soft quilted layer, our queen quilted mattress pad has 100 GSM down alternative fill and a deep pocket skirt that fits mattresses up to 16 inches deep.
Side-by-side comparison
| Mattress pad | Mattress protector | |
|---|---|---|
| Main job | Comfort + everyday protection | Spill, stain and allergen barrier |
| Feel | Soft, quilted, lightly padded | Thin, smooth, sometimes crinkly |
| Waterproof | Usually not | Usually yes |
| Thickness | Thin to medium | Very thin |
| Changes how the bed feels | Slightly | Barely |
| Typical fill | Down alternative or fiber batting | None, just a thin fabric top and backing |
| Washing | Machine washable, check the label | Machine washable, usually low heat |
| Goes on | Over the protector, under the fitted sheet | Directly on the mattress |
Is a mattress pad the same as a mattress cover?
Usually the words describe the same kind of product: a fitted layer that sits on the mattress under the sheet. What matters is what is inside. A quilted pad has fill and adds cushion. A thin cover or protector has none and exists to keep the mattress clean. If a listing does not say whether it has fill or a waterproof layer, it is not telling you which job the product does.
When you need a mattress pad
- Your mattress feels fine but you want a softer, smoother surface
- You want to protect against everyday wear and body oils
- You want a layer you can wash often instead of the mattress
When you need a mattress protector
- You have kids, pets or worry about spills
- You want a waterproof barrier for a new or expensive mattress
- You want an extra layer against dust and allergens
Can you use both?
Yes. The usual order is mattress, then waterproof protector, then mattress pad, then fitted sheet. The protector handles spills and the pad handles comfort. Just check that your fitted sheet is deep enough to cover everything.
What if you want your bed much softer?
Neither a pad nor a protector will change a firm mattress much. For that you want a topper — a 550 GSM bamboo topper for medium plush comfort, or a 1000 GSM pillow-top topper for a deep, sink-in feel. Not sure which? Our guide to 550 vs 1000 GSM mattress toppers compares them, and how to choose a mattress pad covers fit and depth.
How do you pick the right size and depth?
Measure the mattress depth, not just the bed size. A queen is 60×80 inches, but mattresses vary a lot in height, and a pad or protector with a shallow skirt will pull up at the corners on a deep one. Our quilted pad has a deep pocket skirt for mattresses up to 16 inches. If you add a topper later, leave room in your sheet depth for the whole stack.
