Noise may come from the mattress or the base. The best way to determine the source of the noise is to isolate the mattress from the base onto the floor and then attempt to replicate the noise.   BASE ISSUE: There are a number of possible causes of noise with bases, including castors/glides not being fitted correctly, headboard brackets, or the base rubbing against a nearby power point.   MATTRESS ISSUE: Mis-use of the mattress such as sitting, standing or jumping can generate noise. If the noise occurs whilst sleeping, we would suggest contacting our Customer Care Department to discuss the issue further.
