Shopping for the best mattress topper for side sleepers? When you sleep on your side, your shoulder and hip carry most of your weight. On a bed that feels too firm, those spots can feel sore or numb by morning. A good topper adds a layer of cushioning so they can sink in a little.
A topper is also a much smaller purchase than a new mattress, which makes it a sensible first step. Below we explain what to look for, then share five toppers chosen from their Amazon listings, from plush to medium-firm.
How we chose: these picks are based on listing information, not hands-on testing. Details such as included parts, colors, sizes and limits can change, so check the Amazon listing before you buy.

What Side Sleepers Need From a Bed
Side sleeping is a very common position. Cleveland Clinic notes that it can be comfortable for many people and may help with snoring and sleep apnea. It is also the position usually advised in pregnancy.
The challenge is pressure. Your shoulder and hip stick out further than the rest of your body, so they press harder into the mattress. A surface that is too firm pushes back at those points. A surface that is too soft lets your hips sag and can leave you twisted by morning.
What most side sleepers want is a middle ground. The top layer should be soft enough for the shoulder and hip to sink slightly, with enough support underneath to keep your spine roughly straight from neck to hips.
Will a Topper Fix Your Mattress?
A topper changes how the surface of your bed feels. It is a good fix when a mattress is in decent shape but feels too hard, or when you want a little extra cushioning at the shoulder.
It is not a fix for a mattress that sags or has lumps. A soft layer will just follow the dip. If your mattress has a visible sag, it may be time to look at our guide to the best mattresses for different sleepers instead.
Comfort matters for sleep. The NHS lists uncomfortable beds among the common causes of insomnia and suggests making sure your mattress, pillows and covers are comfortable.
How to Choose the Best Mattress Topper for Side Sleepers
- ✓Thickness: 2 inches adds a little softness; 3 inches gives the shoulder and hip more room to sink in.
- ✓Firmness: plush suits a very firm bed; medium or medium-firm suits people who change positions.
- ✓Material: memory foam hugs and responds slowly; gel or graphite infusions are added to help with heat.
- ✓Zoned or flat: zoned toppers vary the feel across the surface; flat ones feel the same everywhere.
- ✓Cover and care: a removable, washable cover is easier to keep fresh than spot-clean foam.
- ✓Staying in place: corner straps or a fitted skirt help stop sliding.
- ✓Setup time: compressed foam toppers often need 24 to 48 hours to expand.
- ✓Return window: it can take a couple of weeks to know if a new feel suits you, so check the return policy.
If you share a bed, think about both sleepers. A side sleeper and a back sleeper may want different firmness, and a medium topper is usually the easier compromise.
Our 5 Picks
TEMPUR-Adapt 3-Inch Mattress Topper (Supreme)
This topper uses the same TEMPUR material the brand puts in its mattresses, according to the listing, which says it adapts to your shape, weight and temperature. The Supreme version is 3 inches thick and described as a medium feel.
For side sleepers, a 3-inch layer gives your shoulder and hip more room to sink in than a thin pad would. The listing also highlights reduced motion transfer, which helps if a partner or pet moves around at night.
Practical details are good here. The cover is removable and machine-washable, and corner straps help keep the topper from sliding around on the mattress.
Who it’s for: Side sleepers who like a slow, hug-like memory foam feel and want a cover they can wash.
Who should skip it: you prefer a bouncy, responsive feel or sleep very hot and want a topper designed mainly around cooling.
From the listing
- ✓3-inch TEMPUR memory foam; medium feel per the listing
- ✓Designed to reduce motion transfer
- ✓Removable, machine-washable hypoallergenic cover
- ✓Corner straps to hold it in place
- ✓Queen size listed at 80 x 60 x 3 inches
Lucid 2-Inch Gel Memory Foam Topper, 5 Zones
The Lucid topper has five raised zones that are meant to ease pressure at different points of the body. Flip it over and you get a flat side, which the listing describes as a more even and firm feel. That gives you two options without buying twice.
It is gel-infused and has a ventilated design for airflow. Like most foam toppers, it arrives compressed and needs 24 to 48 hours to expand fully before you use it.
At 2 inches, it is thinner than the other picks. That can be a plus if your mattress is already fairly comfortable and you only want a little more softness at the shoulder.
Who it’s for: Side sleepers on a mattress that feels a bit too firm, who want to try a zoned surface without a big jump in height.
Who should skip it: your mattress is very firm or sagging. A 2-inch layer may not be enough to change how it feels.
From the listing
- ✓5 raised comfort zones; reversible to a flat side
- ✓Cooling gel infusion and ventilated design
- ✓CertiPUR-US certified foam
- ✓Arrives compressed; 24 to 48 hours to expand
- ✓3-year limited warranty listed
Linenspa 3-Inch Gel Memory Foam Topper
The Linenspa topper is aimed at softening a hard mattress, and its listing lists the firmness as extra plush. That makes it one of the softer options here, which many side sleepers look for at the shoulder and hip.
It is gel-infused to help spread heat, and you can choose a 2-inch or 3-inch version depending on how much change you want. The foam is CertiPUR-US certified, and the listing gives a 3-year limited warranty.
There is no cover in the description, and care is listed as spot clean only. Plan on using a mattress protector or fitted sheet over it.
Who it’s for: Side sleepers on a firm mattress who want a noticeably softer surface without replacing the bed.
Who should skip it: you also sleep on your stomach or back and need firmer support. A very plush layer may let your hips sink too far in those positions.
From the listing
- ✓Plush gel-infused memory foam; extra plush per the listing
- ✓Choice of 2-inch or 3-inch profile
- ✓Arrives compressed; 24 to 48 hours to expand
- ✓CertiPUR-US certified
- ✓Spot clean only; 3-year limited warranty listed
ViscoSoft 3-Inch Select High Density Topper
If plush toppers feel too sinky to you, ViscoSoft’s Select High Density is a more supportive option. The listing describes a medium-firm feel and memory foam with a density of over 3 pounds per cubic foot, which it says is meant to last longer than lighter foams.
The foam is gel-infused for airflow, and the topper is made from a single block of foam rather than a scooped or egg-crate design. It comes in 2, 3 or 4 inches.
It has a removable, washable cover with a zipper. The listing also mentions a 60-day guarantee, which is worth checking since comfort is hard to judge until you have slept on something for a while.
Who it’s for: Side sleepers who switch positions during the night and want some cushioning without feeling stuck in the foam.
Who should skip it: you want the softest possible surface. A medium-firm topper may feel too firm at the shoulder for some side sleepers.
From the listing
- ✓Medium-firm feel per the listing
- ✓Memory foam density over 3 lbs per cubic foot
- ✓Gel-infused foam for airflow
- ✓Removable, machine-washable zippered cover
- ✓Available in 2, 3 or 4 inches; 60-day guarantee listed
Saatva Graphite Memory Foam Topper
Saatva’s listing names side sleepers directly, describing its 3-inch memory foam as body-hugging and pressure-relieving. The foam is infused with graphite, which the brand says helps draw excess heat away from the body.
It has an organic cotton cover, and the listing also mentions reduced motion transfer. The firmness is listed as soft, so expect a cushioned feel.
Care is listed as hand wash only, which is less convenient than a machine-washable cover. As with any foam topper, a protector on top will help keep it clean.
Who it’s for: Side sleepers who tend to feel warm at night and want a soft topper with a natural-fiber cover.
Who should skip it: you want a cover you can toss in the washing machine, or you prefer a firmer surface.
From the listing
- ✓3-inch memory foam; soft per the listing
- ✓Graphite infusion to draw away excess heat
- ✓Organic cotton cover
- ✓Designed to reduce motion transfer
- ✓CertiPUR-US certified
Which Topper Fits You?
Your mattress feels like a board
Go for a plush, thicker layer. The Linenspa 3-inch is described as extra plush, and the Saatva Graphite is listed as soft. Both are aimed at taking the edge off a hard bed.
You change positions during the night
Many people start on their side and roll onto their back. A medium or medium-firm topper, like the ViscoSoft or TEMPUR-Adapt, gives cushioning without letting your hips sink too far when you are on your back.
You sleep warm
Foam can hold heat. Look for gel or graphite infusions, ventilated designs and breathable covers, such as the Saatva or Lucid. Bedding and room temperature matter just as much, and our guide to a cool, dark and quiet bedroom covers both.
You only want a small change
The 2-inch Lucid is the lightest option here, and its reversible design gives you a second feel if the first is not quite right.
A dorm or guest bed
Dorm and guest mattresses are often firm and thin. A 2- or 3-inch foam topper in the right size can make them far more comfortable for side sleepers. Twin XL is a common dorm size, so check that the listing offers it.
Setting Up and Caring for a Topper
- Unroll it on the bed and give it the full expansion time the listing gives, often 24 to 48 hours.
- New foam can have a smell at first. Opening a window for a day or two usually helps.
- Use the corner straps if it has them, then put a fitted sheet over the top.
- A mattress protector over the topper helps with spills, since many foam toppers are spot clean only.
- Rotate it head to foot now and then so you do not always press into the same spot.
- Give yourself a week or two to adjust before deciding whether it works for you.
Do Not Forget Your Pillow
A topper only solves half of the side-sleeping puzzle. Your pillow needs to fill the gap between your ear and the mattress so your neck stays in line with your spine. If your head tips down toward the mattress, the pillow is likely too flat. If it tips up, it may be too high.
Some side sleepers also like a pillow between the knees to keep the top leg from pulling the hips out of line. Cleveland Clinic suggests using pillows to bolster yourself when you try a new position, and it notes that people with back or neck pain often find relief on their back with a pillow under the knees.

When to Talk to Someone About Aches
A topper may make your bed more comfortable, but it is not a treatment for back, hip or shoulder pain. If you wake up with pain that does not ease, pain that keeps getting worse, or numbness or tingling in your arm or leg, see a doctor or physical therapist.
The Cleveland Clinic sleep specialist also advises not forcing a sleep position that is uncomfortable for you, unless a healthcare provider has advised it.

Our verdict
The best mattress topper for side sleepers is one that lets your shoulder and hip sink in while keeping your spine in line. Choose plush if your bed is hard, medium-firm if you change positions, and look for cooling features if you sleep warm. A 3-inch layer suits most side sleepers, and the right pillow finishes the job.
