The Modern Mattress 100-Night Comfort Guarantee is a customer-oriented policy that allows you to try out your new mattress for up to 100 nights in the comfort of your own home. If, within this trial period, you find that the mattress does not meet your comfort needs, you can exchange it for a different model. This guarantee ensures that you have ample time to adjust and assess the mattress's comfort and suitability, providing peace of mind and ensuring your satisfaction with your purchase. If the new mattress is of higher value we ask you to pay the difference, or if it’s of lesser value, you get the difference back. It’s that easy!
