General industry recommendations are to replace your mattress every eight to ten years. Your Aviya Mattress can be expected to exceed this recommendation, but this could depend on how the mattress feels to you and how it may have been used. For example, if you have children that frequently use your bed as a trampoline (NOT recommended!), this could impair the longevity and feel of your mattress. The Aviya comes with a 10-year warranty applicable to specific warrantable issues.
