A mattress arrangement comprising a substantially air-tight support portion, the support portion comprising first and second inter-linked chambers, which are inter- linked so as to allow air to flow therebetween, wherein the first chamber includes a resilient air-retention means, such that, in use, air is able to pass between the first and second inter-linked chambers in dependence upon external pressure applied to the support portion and/or upon decompression of the resilient air-retention means. |
