Traditional mattress stores tell you that you have to try your mattress before you buy it, but you do it under the store lights, with the salesperson waiting for you, dressed in your clothes and shoes, lying on a mattress that many people have tried before. And in 3 minutes you move from one bed to another, trying to decide which one is more comfortable.The 100 night trial period is our solution to this problem. When you buy a new mattress, it takes at least 15-20 days to get used to it. That's why, in our opinion, trying a mattress in the store doesn't always help you choose the right mattress. Instead, we send you a custom-made mattress to your home. As long as you answer our sleep test correctly, we are confident that you will be 95% satisfied with your custom-made mattress. If you have any problems, you are entitled to a free exchange/refund within the 100 night trial period.
