The big difference between Spindle and most other mattress makers is that the company also offers a 25-year Comfort Life program. This allows you to purchase a replacement layer at a 30 percent discount (from prices at the time) at any point during the first 25-years after buying the mattress. This is a more eco-friendly and affordable option for refreshing your sleep situation without having to buy a whole new mattress! Spindle notes that most customers should expect to use their mattress for around eight years. The materials are warrantied for 10 years, however, and the comfort policy applies for 25 years. That means you could switch out a layer to renew your mattress at eight years, 10, years, or even 24 years. Only the original purchaser can use the comfort policy and you have to contact Spindle directly to arrange the discount.
