Side sleepers have a specific complaint about camping and it is always the same one. You lie down, roll onto your side, and within an hour there is a dull ache in the hip or the shoulder because the point of your body carrying the most weight has pushed the pad flat and found the ground underneath it. Back sleepers spread their weight across a whole torso. You concentrate yours on two small areas.
That changes what to look for. A pad that is perfectly warm and perfectly comfortable for someone sleeping on their back can be the wrong pad for you at exactly the same specification. This guide covers what actually stops a hip bottoming out, why width matters as much as thickness for side sleepers, and how to set the pressure so the pad works with you instead of pushing back.

Quick Answer
What sleeping pad works for a side sleeper?
- Thickness is the main filter, because a hip needs more depth than a back does before it reaches the ground.
- Width comes second: side sleepers move, and a narrow pad puts a shoulder on the floor.
- Softer pressure beats firm; a drum tight pad pushes back against the hip instead of cradling it.
- Car camping removes the weight penalty, so buy the thick version rather than the packable one.
Bottom line: go thicker and wider than a back sleeper would, then run it softer than feels right at first.
Why Side Sleeping Bottoms Out a Pad
Lying on your back spreads your weight over shoulders, back and hips at once. Lying on your side puts most of it through the hip and the shoulder, two narrow contact points, which means the pressure per square inch at those spots is far higher and the pad compresses much further underneath them.
Once the pad compresses fully, you are effectively resting bone on ground with a thin layer between, and that is the ache people describe. The pad has not failed, it simply ran out of depth before your hip stopped sinking, which is why thickness is the first specification to look at.
How Much Thickness Is Enough
The practical test beats any number. Lie on the pad on a hard floor at home, on your side, in your normal sleeping position, and reach underneath at the hip. If you can feel your hip pressing through to the floor, the pad is too thin for you regardless of what it says on the box.
Manufacturers publish pad thickness in the listing, so you can compare directly, but bodies differ enough that the same pad bottoms out for one person and not another. Buy from a retailer with a straightforward return policy and do the floor test the day it arrives.
Thickness Is Not Warmth
A thick pad can still be a cold pad. Insulation is described by R value, measured across the industry with the ASTM F3340 method, and that figure depends on what is inside the pad rather than how tall it is. Check both numbers instead of assuming one implies the other.
For side sleepers this matters twice over, because a hip pressed deep into a pad compresses the insulation at exactly the point where your body is closest to the ground. Our R value guide covers how to read the figure.
Width and the Shoulder Problem
Side sleepers roll, tuck a knee forward and put an arm out, which uses more lateral space than lying flat on your back. On a standard width pad the result is a shoulder or an elbow off the edge and onto the tent floor several times a night.
Wide and extra wide pads solve it for the price of trunk space you are not paying for anyway when you drive to the site. If you sleep next to a partner, a double width pad also removes the cold gap where two singles meet.
Pads for Side Sleepers by Situation
Best for maximum hip clearance
A thick insulated air or self inflating pad gives the most depth before your hip reaches the ground, which is the core requirement here.
Best without a pump
A wide self inflating pad reaches usable depth on its own and lets you fine tune pressure by opening the valve for a few seconds once you are lying on it.
Best for couples where one sleeps on their side
A double width pad avoids the seam between two singles, which is where a side sleeper’s knee tends to land.
Best for adding depth to what you already own
A closed cell foam pad underneath an existing pad adds depth and insulation cheaply, and it does not depend on air pressure to keep working.
Setting the Pressure
| Pressure | How it feels | Effect on the hip | Verdict for side sleepers |
|---|---|---|---|
| Fully firm | Drum tight, bouncy | Pushes back, no contour | Usually too hard |
| Slightly soft | Gives under the hip | Hip settles in, spine stays level | The target |
| Very soft | Sinks noticeably | Bottoms out on the ground | Too little support |
| Foam under a pad | Firm base, soft top | Depth without bottoming out | Best for cold, hard ground |
Common Mistakes
The most common mistake is inflating to maximum firmness because that feels supportive when you press it with a hand. Lying on your side, a rigid pad has nowhere to give, so your hip carries all the load instead of sinking into a hollow that spreads it. Let air out until your hip settles without touching the floor.
The second is treating a camping pad as a treatment for pain you already have. If hip or shoulder pain is a problem at home as well as at camp, that is worth raising with a clinician rather than solving with gear. A pad changes how weight is supported, and that is the honest limit of what it does.
Frequently Asked Questions
How thick should a sleeping pad be for a side sleeper? Thick enough that your hip does not reach the ground when you lie on your side on a hard floor. Test it at home rather than trusting a single number, since body weight and hip shape vary.
Are air pads or self inflating pads better for side sleepers? Air pads generally reach more depth for the packed size, while self inflating pads are easier to set softly without a pump. Both work; depth and adjustability matter more than the category.
Should I inflate the pad firm or soft? Softer than feels right when you first press it. A firm pad resists the hip rather than letting it settle.
Will a thicker pad also be warmer? Not automatically. Insulation is described by R value and depends on the pad’s internal construction, so check that figure separately.
Does a cot help a side sleeper? Only with a pad on it, since a taut deck has no give at the hip. See our cot mattress guide for how to layer it.
What if the pad still hurts my hip? Add a foam layer for depth, drop the pressure, and try a wider pad so your arm is not pulling your shoulder forward. If pain persists across setups, talk to a clinician rather than buying more gear.
The Bottom Line
Side sleepers need depth and width more than back sleepers do, and they need the pad set softer than instinct suggests. Test for bottoming out on a hard floor at home, check the published R value separately from the thickness, and use the fact that car camping does not charge you for bulk.
