Eight, the startup formerly known as Luna, announced today that it has raised $6 million in Series A funding.

The company makes a smart mattress cover that can track your sleep, change temperature (the temperature can even vary across different parts of the cover) and send data to other Internet-connected devices. It says it has sold 6,000 units through crowdfunding and pre-orders.

Co-founder and CEO Matteo Franceschetti said many of those pre-orders come from people who don’t want to wear sleep-tracking devices: “A lot of people using wearables don’t want to use wearables in the night. We are the complementary device that they were missing till now.”

Eight’s next step is to actually fulfill those preorders, which it plans to do this spring before making the smart cover generally available in the summer.

The new funding comes from Y Combinator, Yunqui Partners, Azure Capital, Cota Capital, Comcast Ventures, Vast Ventures, Stanford University (through its StartX incubator), Galvanize Ventures and YC partner/Scribd co-founder Jared Friedman.
