A side sleeper's weight rests on the shoulder and the hip, two small areas, instead of spreading across the whole back. That is why a firm mattress can feel harsh on the side and fine on the back. A topper changes the top layer of the bed, and the thicker the layer, the more your shoulder and hip can sink in. Our side sleeper toppers page lists the options, and the guide below explains how to choose among them.
What should a side sleeper look for in a queen mattress topper?
Five things matter, in roughly this order.
- Loft. The thickness of the fill decides how far the shoulder and hip can sink in. More loft means a deeper pocket for the body.
- Fill weight. For fiber-filled toppers, GSM tells you how much fill is inside. A higher number means more cushion.
- Surface breathability. Side sleepers who sink into a topper are surrounded by more material, so a breathable cover helps.
- Fit. A deep-pocket elastic skirt that matches your mattress depth keeps the topper from shifting when you turn over.
- Washability. A topper that can go into a home machine is easier to keep fresh.
How much loft does a side sleeper need?
The answer depends on the mattress underneath. On a soft mattress that already lets the shoulder and hip sink in, you may need very little extra. On a firm mattress, a thin topper can still feel like lying on a board with a blanket over it. A thicker, higher-loft layer gives the shoulder and hip room to settle before they meet the firmer layer below.
If your mattress is firm, our guide on a mattress topper for a firm mattress matches loft to how firm the bed is. The short version is that slightly firm beds do well with 550 GSM and very firm or worn ones usually call for 1000 GSM.
Which NOVASTILE queen topper suits side sleepers?
We sell two queen toppers. Both are 60 by 80 inches, with a bamboo viscose and polyester cover, down alternative fill and an elastic deep-pocket skirt.
| 550 GSM | 1000 GSM | |
|---|---|---|
| Loft | Medium plush | Ultra plush, high loft |
| Cushion at shoulder and hip | Noticeable, you stay near the surface | Deep, you sink in |
| Warmth | Lighter fill, sleeps cooler | More fill, sleeps warmer |
| Mattress depth it fits | 8 to 20 inches | Up to 21 inches |
| Best match | Slightly firm mattress, warm sleepers | Firm or worn mattress, side sleepers wanting a deep layer |
| Price (queen) | $36.00 | $59.99 |
The 1000 GSM ultra plush topper is the one we generally suggest to side sleepers, because the extra fill gives the shoulder and hip the deepest cushion we offer. The 550 GSM medium plush topper is the better pick for a side sleeper whose mattress is only a little firm, or who wakes up warm.
What if I sleep on my side and run hot?
This is the trade-off most side sleepers face. A high-loft topper gives cushion and also adds insulation. A bamboo viscose surface is breathable and moisture-wicking, which helps, but the amount of fill under it still matters. If heat bothers you more than firmness does, start with the 550 GSM.

Keep a realistic expectation: no fiber-filled topper feels cold. For a closer look at what a bamboo viscose surface does and where it stops helping, read our cooling mattress topper guide or browse the cooling mattress toppers page.
Should side sleepers choose fiber fill, foam or latex?
Each material feels different. Fiber fill, which is what a down alternative topper uses, gives a soft, lofty, pillow-top feel. Memory foam contours closely and holds its shape. Latex is bouncy and springs back. Side sleepers use all three, so the choice comes down to the feel you like.
| Material | Feel | Things to weigh |
|---|---|---|
| Down alternative fiber | Soft, lofty, pillow top | Machine washable, lighter to handle, needs shaking to restore loft |
| Memory foam | Contouring, slow to respond | Can hold body heat, usually spot cleaned |
| Natural latex | Springy, supportive | Heavier, usually spot cleaned |
Our comparison of bamboo, memory foam and down alternative toppers goes deeper, and the down alternative vs natural latex guide covers the other end of the spectrum.
How do I stop a topper from shifting when I roll over?
Side sleepers move more at the edges of the bed, so slipping toppers are a common complaint. Three habits help. Measure your mattress depth, including any pad, and pick a topper whose pocket depth covers it. Pull the elastic skirt fully around each corner. Smooth the topper flat before you put the fitted sheet on top.

How should side sleepers care for a high-loft topper?
High-loft fiber compresses where you sleep, so shake it out regularly. Our care routine is to shake it vigorously for up to five minutes, allow 24 to 48 hours for full loft after washing or unpacking, wash on a gentle cycle at 30 degrees Celsius or cooler, skip the bleach and tumble dry with no heat. Rotating the topper end to end every few months spreads out wear.
What mistakes do side sleepers make when buying a topper?
- Buying the thinnest option on a firm mattress. A light layer on a very firm bed often changes less than people expect, and the shoulder and hip still meet the firm layer underneath.
- Ignoring mattress depth. A mattress with a pad already on it can be deeper than the label suggests. A skirt that is too shallow pops off at the corners, usually in the middle of the night.
- Forgetting the sheets. A thick topper raises the bed, so a fitted sheet with shallow pockets may not stay on. Check your sheet pocket depth before you order a high-loft topper.
- Choosing only on softness. A topper that feels wonderful for the first minute can feel too warm after an hour. Think about heat as well as cushion.
- Skipping care. Fiber loses loft where you sleep if it never gets shaken out, and a topper that looks flat is often just compressed.
How do I know the topper is working for me?
Give it a week of normal nights. Pay attention to three things: how your shoulder and hip feel when you lie down on your side, whether you wake up warm, and whether the topper stays where you put it. If the cushion is not enough, a higher fill weight is the next step. If you are too warm, a lighter one is the next step. Those two adjustments cover most of what side sleepers run into.
It also helps to make one change at a time. Swapping the topper, the pillow and the sheets on the same night makes it hard to tell which one changed how the bed feels. Add the topper first, sleep on it for several nights, and adjust your pillow height afterward, because a thicker bed surface changes how high your head sits relative to the mattress.
How do the two NOVASTILE toppers fit the bed?
The 550 GSM topper has an elastic deep-pocket skirt for queen mattresses 8 to 20 inches deep, which covers most standard and pillow-top mattresses once you account for a pad. The 1000 GSM topper fits queen mattresses up to 21 inches deep. Both are 60 by 80 inches and both are sold as a single piece in green. Measure from the bed frame surface to the top of the mattress, add the thickness of any pad, and compare the number to the depth range.
