What is so special about the springs?
The ClimaLuxe and Airpulse spring are manufactured from a TPE (thermo-plastic elastomer) containing a high level of polymeric material. The proportion of polymeric material used in the BICO springs is far higher than normally used for standard plastic (particularly the middle section which is soft and contains the highest level of polymeric material). It is this high quality mix of ingredients in the TPE that makes the BICO springs soft, resistant and long lasting.
