The sleep trial period is an important part of the mattress buying experience. Many people think they can just sit down on a mattress in the store and let that be that. But mattresses have to go through a “break-in” period for you to know how they’re going to feel. This break-in period usually lasts around 90 days.
That means you need at least a 100-night sleep trial period. A 100-night sleep trial period allows you to break in the mattress and sleep on it a few nights afterward. A 100-night trial can ensure you know exactly what you’ll be sleeping on for the next decade or more.
