Overview of Features

Technology Details

The Saturn+ is 10 in height and blends together three foam layers:

The initial layer is a 2 Responsive Foam. As the name suggests, it is designed to give the sleeper a remarkable quick responding surface, similar to the feel of latex. The resilient layer helps you sleep on the mattress, rather than in the mattress. You can quickly change your sleeping position at night as it provides freedom of movement. This foam is super comfortable and superbly supports your back and other pressure points.

The 2 thick Transition Foam aims to give you enhanced support and proper pressure-relief. For anyone suffering from achy mornings, the Saturn+ helps to reduce the inflammation and de-stresses your joints. The transitional layer serves as a perfect medium to let you adjust from the bouncy Responsive Foam to a firmer Supportive Foam. If you change your sleeping position often while slumbering, with Saturn+, you and your partner can enjoy an uninterrupted sleep due to its motion isolating property.

The base layer is a 6 thick Supportive Foam, built especially for a strong and sturdy foundation, increasing the lifespan of the mattress. The Supportive Foam Layer is denser and firmer than the surfaces above and assists in maintaining the structure and durability of the mattress.

Smart Technology Details:

If you are a tech-savvy person who likes being informed and aware of how you sleep, you may add a smart cover on top of the Saturn mattress. The smart technology connects to your home WiFi and helps you change your sleep environment during the night.

For example, you can adjust the rooms thermostat easily from a click on the app. You can also set a smart alarm that wakes you up at the best time when you are fully rested.The Eight Sleep app provides you with a detailed report daily with relevant health and sleep metrics information.

Additionally, the best part is that the smart technology does not require you to carry any gadgets. It is an entirely non-wearable sleep tracking device.
