Sweet Night was founded in July 2011, launched high-quality and humanized mattress products and integrated sleep industry resources, and perfected the sleep industry chain to create Sweet Night’s unique "sleep ecosystem", which allows people to have quality sleep in a simpler and more convenient way. It was since then, we have had a goal: To make Sweet Night a leading global brand of sleep to serve all humanities. With this mission, we stepped on a challenging road... All of our products are designed to ensure the perfect sleeping experience and are made from breathable & hypoallergenic foam. The foam also has anti-dustmite properties and provides enough pushback to allow for ergonomic support in all sleeping positions.
