One pair of Sleeeps® will last one month (based on regular use per night) depending on how they are handled, used, and your body chemistry (earwax, oils, etc.). Naturally, increased use will decrease their life.
To ensure that your Sleeeps® last as long as possible, we would recommend that you follow our fitting guides and cleaning instructions.
It is important that your Sleeeps® are regularly inspected for serviceability and are maintained in accordance with our instructions. Be sure to replace your Sleeeps® monthly or when they start to “flake”, tear, or lose their memory foam properties (e.g. the foam expands quickly rather than slowly).
