We do everything we can to accommodate your size and comfort preferences. Some of our mattresses can be customized to be slightly shorter or taller, but there are some that cannot. In order to change the height of a mattress, a component or layer is either added or removed, followed by a customization of the border and fabric materials. It is important to keep in mind that this does change the comfort level of the mattress. Feel free to contact us and we can assist in finding the right solution.
