Helix

Helix Sleep is a U.S.-based mattress brand founded in 2015 with a focus on personalized comfort rather than generic one-size-fits-all beds. 

Instead of offering just a few firmness options, Helix uses an online sleep quiz that asks about your sleep position, body type, and firmness preference to recommend the best match from its lineup. Their mattresses are typically hybrid designs combining individually wrapped coils with foam layers for balanced support, pressure relief, and cooling airflow.

Headquartered in New York City, Helix designs and assembles its mattresses in the U.S., and offers risk-free trials plus free shipping on many models
