How do I know when it's time to replace my old mattress?
We recommend every 7-10 years. But, if you’re waking up with aches and pains, can feel the springs or notice a visible dip in the middle, it’s time to see us.
I'm a side sleeper; is this mattress good for me?
Yes, we recommend a soft or medium mattress. This allows your shoulders and hips to sink in slightly, keeping your spine aligned.
