The dimensions of our mattresses refer to the sleeping area/mattress size of the bed - from edge to edge. All Australian mattresses are standard sizes. When measuring bed frames in wood, metal or fabric these will often have an overall width and length greater than the sleeping area due to the nature of the beds construction. Be sure you are measuring correctly when determining your size.

Special sizes:  some of our models can be made to a specific size.  If you have an older bed frame or European frame you may need to have a mattress made to your specific dimensions.
