The Short Answer
| Mattress Pad | Mattress Topper | |
|---|---|---|
| Thickness | Usually under 1" | Usually 1–4" |
| Main job | Light softness and protection | Change how the bed feels |
| Changes firmness? | Barely | Yes |
| Fixes a too-firm bed? | No | Yes |
| Fixes a too-soft bed? | No | A firm topper can |
| Washable? | Often | Rarely (covers may be) |
| Price | Lower | Higher |
Get a topper if your mattress is uncomfortable: too firm, too soft or too warm. Get a pad if your mattress feels fine and you want a little extra softness or protection.
What Is a Mattress Pad?
A mattress pad is a thin, quilted layer that fits over your mattress, usually like a fitted sheet. It adds a little cushioning and helps protect the mattress from sweat and everyday wear. Some pads are waterproof; many aren't.
Common pad materials: cotton, wool, polyester fill, down alternative.
Best for: Adding a thin, breathable layer without changing firmness
| Type | Mattress pad |
|---|---|
| Material | Washable wool |
| Thickness | 0.5" |
| Firmness | Barely changes the feel |
| Sizes | Crib to Cal King |
| Cover | Cotton percale, 270 TC |
| Certifications | OEKO-TEX Standard 100 (cover and wool) |
| Trial | See Sleep & Beyond's current terms |
| Warranty | 5-year |
- Thin natural layer that helps manage moisture
- Fits crib through Cal King
- 5-year warranty
- Won't fix a mattress that's too firm or too soft
- Not waterproof
Sleep & Beyond's myPad is a half-inch wool pad in a cotton percale cover. It's an example of what a pad does well: it adds a breathable, moisture-wicking layer without changing the mattress's firmness. It comes in crib through Cal King.
What Is a Mattress Topper?
A mattress topper is a thicker, removable layer, usually 1 to 4 inches, that rests on your mattress. It changes how the bed feels: softer, firmer, more contouring or more breathable, depending on the material.
Common topper materials: latex, memory foam, wool, down or feather, polyfoam.
Best for: Most sleepers who want natural, durable cushioning or firmness, with the widest firmness choice

| Cover | Optional GOTS organic cotton cover, sold separately |
| Certifications | GOLS, OEKO-TEX Standard 100, GREENGUARD Gold |

| Warranty | 5-year limited |
- Widest firmness range of the toppers we cover, from Soft to Extra-Firm
- Certified organic latex with ventilation holes for airflow
- Can soften a firm bed or firm up a soft one, depending on the firmness you choose

The PlushBeds Organic Latex Topper shows what a topper can do that a pad can't: it comes in 2 or 3 inches and from Soft to Extra-Firm, so it can make a bed noticeably softer or firmer. See our best mattress topper guide for more options.
What About Mattress Protectors?
A protector is the thinnest layer. Its job is to keep liquids, sweat, dust mites and allergens out of your mattress. Many are waterproof. It doesn't add comfort, but it protects your mattress and topper.
| Layer | Purpose | Thickness |
|---|---|---|
| Protector | Protection | Thin |
| Pad | Light comfort plus some protection | Under 1" |
| Topper | Changes the feel | 1–4" |
Sleep & Beyond's organic cotton waterproof mattress protector uses organic cotton with a waterproof membrane.
Which One Do You Need?
| Your Situation | Choose |
|---|---|
| Bed is too firm | Topper (soft latex or memory foam) |
| Bed is too soft (not sagging) | Topper (firm latex) |
| Sore shoulders or hips | Topper, 3" |
| Sleep hot | Wool pad or latex/wool topper |
| Bed feels fine; want protection | Protector |
| Bed feels fine; want a little softness | Pad |
| New mattress you want to keep clean | Protector or pad |
| Mattress sags | Neither; replace the mattress |
Pros and Cons
Mattress Pads
| Pros | Cons |
|---|---|
| Lower cost | Won't fix comfort problems |
| Often machine washable | Wears out faster than a topper |
| Adds a little softness | Many aren't waterproof |
| Easy to put on and take off | Thin, so the effect is subtle |
Mattress Toppers
| Pros | Cons |
|---|---|
| Changes the feel of the bed | Costs more |
| Can soften or firm a bed | Usually not washable |
| Extends the life of a good mattress | Can slide around |
| Wide range of materials | Some aren't returnable once opened |
Can You Use a Pad and a Topper Together?
Yes, and it's a common setup. Layer it this way:
- Mattress
- Topper
- Pad or protector (fitted over both if deep enough)
- Fitted sheet
The pad or protector keeps the topper clean, since most toppers can't be washed. A deep-pocket pad also helps hold the topper in place.
Pad and Topper Materials Compared
| Material | As a Pad | As a Topper |
|---|---|---|
| Cotton | Breathable, washable | Rare |
| Wool | Breathable; moisture-wicking | Soft cushioning; temperature regulation |
| Latex | Rare | Supportive; soft to extra-firm |
| Memory foam | Rare | Deep contouring; can run warm |
| Down or feather | Light softness | Plush, little support |
| Polyester fill | Inexpensive | Inexpensive; flattens faster |
Waterproof Pads vs. Protectors
Some pads are waterproof, which blurs the line with protectors. The difference is mostly in feel: a waterproof pad adds a little cushion, while a protector is thin and smooth. If you need waterproofing for a child's bed, for spills or for incontinence, look for a fully waterproof layer and check that it's breathable, since some plastic-backed layers trap heat.
What to Buy First for a New Mattress
| Your Situation | Buy First |
|---|---|
| New mattress that feels right | A protector |
| New mattress that's too firm | Use the trial first; then a topper |
| Older mattress that's still supportive but uncomfortable | A topper, then a protector over it |
| Kids' bed | A waterproof protector |
How Long Do Pads and Toppers Last?
It depends on materials and care. Thin pads typically wear out sooner than toppers. Latex toppers generally last longest. Warranties are a rough guide: Sleep & Beyond lists a 5-year warranty on its wool pads and toppers; PlushBeds and Eco Terra list 5 years on their latex toppers.

Frequently Asked Questions
What's the Difference Between a Mattress Pad and a Topper?
A topper is thicker, usually 1 to 4 inches, and changes how the mattress feels. A pad is thinner, usually under an inch, and adds light softness and some protection without changing the feel much.
Which Is Better, a Mattress Pad or a Topper?
It depends on your goal. If your bed is too firm, too soft or uncomfortable, get a topper. If your bed feels fine and you want a little softness or protection, get a pad.
Can I Use a Mattress Pad and a Topper Together?
Yes. Put the topper on the mattress, then the pad or protector over the topper. The pad helps keep the topper clean.
Is a Mattress Protector the Same as a Pad?
No. A protector is a thin barrier, often waterproof, designed to keep liquids and allergens out. A pad adds some padding and may or may not be waterproof.
Are Mattress Pads Washable?
Many are, but not all. Check the care label. Wool pads may need gentle washing or airing.
Do I Need a Pad If I Have a Protector?
Not necessarily. If your bed already feels right, a protector alone is enough. Add a pad if you want a little extra softness.
The Bottom Line
A topper changes how your bed feels; a pad adds a thin layer of softness and protection. If your mattress is uncomfortable, start with a topper like the PlushBeds Organic Latex Topper. If it feels fine and you just want a breathable extra layer, a pad like Sleep & Beyond's myPad is enough. And either way, a protector keeps everything underneath clean.
