Quick answer

Most camping mattress noise comes from trapped air shifting in the drop-stitch base or from an under-inflated pad. For a HEST Sleep System, the fix usually involves fine-tuning the air pressure with the HEST Pump or checking the foam layer for proper seating. If the noise persists, the cause is likely structural and may require a replacement.

Symptom: Crinkling or Popping Sounds at Night

If your camping mattress pad makes crinkling or popping sounds every time you shift, the most common culprit is trapped air moving inside the drop-stitch base. This happens when the mattress is under-inflated, allowing the internal air chambers to flex and rub against each other. Over-inflation can also cause popping as the fabric strains at the seams.

Likely Cause: Air Pressure That's Too Low or Too High

For a HEST Sleep System, the drop-stitch base is designed to be firm but not rock hard. If you're hearing noise, check the pressure by pressing on the center of the mattress. A properly inflated pad should have minimal give under your weight. Use the HEST Pump to add or release air in small increments until the noise stops. The pump's compact design makes it easy to carry for on-the-spot adjustments.

Corrective Action: Adjust the Air and Check the Foam Layer

Start by deflating the mattress completely, then re-inflate to a firm but comfortable level. If the noise is a low rumble rather than a crinkle, the memory foam topper may be shifting on the base. Lift the foam layer and reseat it, ensuring it lies flat without wrinkles. For persistent noise, try sleeping on the mattress for a few minutes with the valve open—this equalizes internal pressure and often resolves the issue.

Diagnosis checklist

  • Symptom: Crinkling, popping, or rumbling sounds when you move on the mattress. If you hear noise only during movement, the cause is likely air-related.
  • Likely cause: Under-inflated drop-stitch base allowing internal chambers to flex, or over-inflated seams straining. Adjust air pressure with the HEST Pump in small increments until noise stops.
  • Corrective action: Deflate and re-inflate the mattress, reseat the memory foam topper, and test with the valve open. If noise disappears after adjustment, the fix is complete. If not, proceed to the next step.
  • Stop or choose another option: If noise persists after all adjustments and reseating, the drop-stitch base may have a manufacturing defect or internal damage. Contact HEST support for a replacement recommendation.
