How to Choose a Mattress Topper for Your Sleep Position
Match a topper's cushioning to your usual position, then check how it feels with your mattress and whether you can turn easily.
In brief, choose a mattress topper for the position you sleep in most, and consider how it will feel on your existing mattress. Side sleepers may want more cushioning at the shoulder and hip; back and stomach sleepers may prefer a steadier, less plush feel. If you change positions, notice how easily you can move.
Three things to remember
- Start with your usual sleep position, not the thickest topper.
- Think about the topper and mattress together.
- Check fit and return terms, then try your usual positions.
Match the feel to your sleep position
The position you use most is a useful place to start. Firmness labels vary by brand, though, and your own preference matters more than a label.
| Sleep position | Starting point | What to notice |
|---|---|---|
| Side | Try a softer feel if you'd like more cushioning. | Your shoulder and hip should feel cushioned without the layer feeling too deep. |
| Back | Look for a moderate, balanced feel. | Notice whether your middle feels supported rather than deeply sunk in. |
| Stomach | Begin with a thinner or firmer option. | Check whether your middle settles much farther into the bed than the rest of you. |
| Combination | Compare surfaces that feel comfortable in each position you use. | See whether you can turn over without feeling stuck in the layer. |
Think about the feel you want, too. A suggestion in the table can narrow your search, but you'll still want to judge the surface in your own usual position.
Consider the mattress underneath
A topper adds a comfort layer; the mattress underneath still does much of the work. The same plush layer can feel different on a firm bed than on one that's already soft.
Thing is, extra cushioning won't repair a damaged surface. If your whole bed feels too firm, a topper may give you the adjustment you're looking for, but it won't reliably level a pronounced dip or fix damaged springs or a bending frame.
Compare a contouring feel with a springy one
Memory foam tends to conform more closely, while latex generally feels bouncier, according to Mattress Nut's material comparison. Both are starting points for comparing feel.
If you change positions often, pay attention to what happens when you roll over as well as how the layer feels when you're lying still. Thickness and firmness make a difference, too, so the material name alone won't tell you exactly what to expect.
Decide how much thickness you want
Toppers commonly add about 2-4 inches, according to Mattress Nut's sizing guide. Treat that as a shopping range, not a rule.
More thickness puts more material between you and the mattress and can change the bed's feel more noticeably. That's not automatically better. A deeper foam layer may feel warmer or make turning over harder for some people, so it helps to decide whether you want a noticeable cushion or just a smaller adjustment to the bed you have.
Check the fit and everyday details
Get your mattress measurements before you order, then compare them with the topper listing. Check the fitted sheet as well: its pocket depth needs to accommodate the combined height of the mattress and topper.
Look at upkeep and returns before checkout, too:
- A removable cover and clear cleaning instructions can make upkeep simpler.
- Some toppers may not be returnable, and the available test period can affect your choice.
Your pillow's feel is worth considering if you're adjusting the rest of the bed. LilyPillow's buckwheat pillow has adjustable fill, so you can add or remove hulls to change its feel.
Test the topper on your own bed
Follow the manufacturer's setup instructions first. Then lie in each position you normally use, stay still for a while, and roll over. Notice the cushioning and springiness, including whether movement feels comfortable.
An at-home trial, if the seller offers one, gives you time to judge the whole bed over a night or more. Keep the return deadline in mind, and leave yourself enough time to decide whether you like the topper with your mattress in your usual positions.
The bottom line
Start with the feel that suits your main sleep position, then consider the mattress beneath it and how easily you like to move. Before ordering, measure your bed and read the return terms.
