Comfort life (how long it will feel brand new) is 12-14 years on the standard Chattams (including Kingsbury), and 18-22 years at the top of the line.

Hello - the comfort life is very long, however our body’s change and need different support as they do. So the beds comfort may feel different to you after 8-10 years however the beds will last much longer

I had a julianna for 14 years. It was a 15 1/2 high model and the best mattress I ever had. Unfortunately they stopped making this model in 2012. I got a new one because I wanted more firmness and some spots were getting low from where I slept. Otherwise I could have kept it longer.

I have had a top of the line Chattam and Wells for 21 years. It is the most comfortable bed I have ever slept on. It has developed mountains and valleys, and I am now looking to replace it with a new one 20 years later.
