Our mission is to address confusion over choosing the right mattress and an increasingly one-size-fits-all response by the online mattress market. Unlike competitors who offer single mattress solutions, our custom sleep quiz recommends mattresses tailored to how you sleep at night, which has been studied to help you sleep longer and more comfortably each night. Each of our three mattress collections is designed and assembled at our Arizona facility, where our materials science team makes our own coils, pours our own CertiPUR-US certified foams, and handcrafts mattress components. All Helix mattresses are free from fiberglass.
