All our mattresses are designed to be ergonomic - meaning they ensure optimal spinal alignment. Every one of our best sellers have been thoroughly tested by and won awards from independent consumer associations across Europe in no small part because of this. Between the models, we've worked to deliver progressively more comfort, support, and thermal regulation by the addition of more innovative materials. On top of these: all our mattresses are designed to be motion isolating, super easy to clean with removable covers, and made with materials certified to be safe even for babies. If you're still unsure, get in touch with our Emma Sleep Experts, who will be happy to help you find the right sleep system for you.
