A basic cot gives you a flat, elevated surface to sleep on, but it’s rarely comfortable on its own. The taut fabric stretches across a rigid frame, creating pressure points at your hips and shoulders while the metal rails dig into any limb that drifts to the edge. A few targeted upgrades can turn a cot into a genuinely good sleeping setup, whether you’re camping, staying in a bunk at summer camp, or hosting overflow guests at home.
Add a Foam Topper or Sleeping Pad
The single biggest improvement you can make is putting a layer of cushioning between you and the cot’s fabric. A memory foam topper in cot size (typically 30 by 75 inches) adds enough give to relieve the pressure points that form at your hips and shoulders on a flat surface. Look for a topper that’s at least two inches thick. Anything thinner compresses too quickly under body weight and stops doing much after the first hour. A density around three to four pounds per cubic foot hits the sweet spot between softness and support.
If you don’t want to buy a dedicated topper, a closed-cell foam sleeping pad works well and packs down smaller for camping. Self-inflating pads are another option. They conform to your body better than rigid foam and add an insulating air layer beneath you. In cold weather, that air layer matters more than comfort because a cot suspends you off the ground, exposing your underside to circulating cold air that pulls heat away faster than sleeping on the ground would.
Pad the Frame Rails
Cot frames are made of aluminum or steel tubing, and rolling into one of those rails in the middle of the night is an instant wake-up. Pool noodles are the classic fix here. Slit a pool noodle lengthwise along one side and press it over the side rail. It creates a soft bumper that cushions contact and, for kids especially, acts as a subtle barrier that makes it harder to roll off the edge entirely. You can secure the noodle with a few strips of duct tape or zip ties so it doesn’t shift around.
For the crossbars underneath, wrapping them with pipe insulation foam (the kind sold at hardware stores for a few dollars) keeps them from pressing up through the fabric when the cot sags under your weight. This is especially useful on older or cheaper cots where the fabric has stretched over time and hangs lower between supports.
Level the Cot on Uneven Ground
A cot that tilts or rocks will keep you half-awake all night, even if the surface itself is comfortable. On uneven ground at a campsite, you have a few simple options. The easiest is scooping out a shallow depression under whichever leg sits higher, bringing the frame level without needing any extra gear. If the ground is too hard for that, stack flat rocks, folded clothing, or pieces of firewood under the lower legs to bring them up.
A more deliberate approach is cutting strips from an old foam sleeping pad and keeping them in your camp kit specifically for shimming cot legs. They compress just enough to grip the ground, they don’t slide on dirt or rock the way hard objects can, and they weigh almost nothing. Four-legged cots are easier to level than two-legged designs because you can adjust each corner independently.
Fix the Squeaking
Cot joints squeak because metal rubs against metal at the hinges and connection points. Every time you shift your weight, the friction produces a creak that can wake you (or everyone else in the tent). The fix is simple: apply a small amount of grease or lubricant to every joint and moving part on the frame. A copper-based anti-seize compound works particularly well because it stays in place, handles temperature swings, and doesn’t wash off with moisture the way lighter oils do. White lithium grease is another good option.
If you don’t have lubricant handy, a strip of duct tape wrapped around the contact point between two metal pieces can dampen the noise enough to get through a trip. For a more permanent solution, disassemble the cot, clean the joints, apply grease, and reassemble. The squeak usually won’t come back for a full season.
Layer Your Bedding Strategically
What you put on top of your topper matters more on a cot than on a regular bed. A fitted sheet keeps everything anchored so your topper doesn’t slide around when you move. Cot-size fitted sheets exist, but a twin sheet pulled tight and tucked under also works. On top of that, a sleeping bag or blanket layered with a fleece liner gives you adjustable warmth without bulk.
If you’re using the cot in humid conditions or warm weather, a breathable cotton or moisture-wicking sheet between your body and the foam prevents the clammy feeling that builds up when skin sits directly on memory foam. Foam doesn’t breathe well on its own, and the cot’s fabric underneath traps moisture from below. A thin breathable layer on top lets enough air circulate to keep you dry through the night.
Choose the Right Pillow Setup
A cot’s narrow width means a standard bed pillow often hangs over the edges or slides off entirely. A compact camping pillow or a stuff sack filled with soft clothing stays put better and takes up less space. If you’re a side sleeper, pillow height matters even more on a cot because the firm surface doesn’t let your shoulder sink in the way a mattress would. You need a thicker pillow to keep your neck aligned, or you can fold a regular pillow in half to get the extra loft.
Placing a small rolled towel or piece of clothing under your knees can also relieve lower back pressure if you sleep on your back. On a cot’s flat surface, your lumbar spine gets no support unless you create some, and that simple roll can be the difference between waking up stiff and waking up rested.
