    (Technická Univerzita v Liberci, 2010-01-01) Wangkanai, Puvisit; Havelka, Antonín
    This master thesis studies the characteristic differences of structure group in mattresses and physiological of mattress materials, therefore we can define mattress structure in three groups; they are 1. with core mattress, 2. Fluid core mattress, and 3. without core mattress or futon mattress. This part can be summarizing by comparing the advantages and disadvantages in mattress groups in today. On the other hand thesis shows a sample of mattress materials; that use today, HR3836,T2140, TC50M, and Latex materials( Matrace Gumotex a.s, Czech Republics). In the testing method reference of ISO 11092 Textile Physiological effects- Measurement of Thermal Resistance and Water- vapour Resistance under steady-state conditions( sweating guarded- hotplate test) The physical properties of textile materials (Foam materials)which contribute to physiological comfort involve a complex combination of heat and mass transfer.
