To decide which Helix or Saatva mattress will best suit your sleeping style and preferences, consider the following factors:

Certificates: Saatva and Helix are GREENGUARD Gold and Certi-PUR certified, but Saatva is additionally certified organic and safe by GOLS and eco-INSTITUT. This means that over 95% of textiles and latex are certified organic. GOLS certified mattresses also have an extensive list of banned substances and are manufactured to protect the environment. Both Helix and Saatva design and manufacture their products in the United States, but Saatva goes above and beyond to share transparently how its mattresses are made.

hardness: Whether you like to sink into a plush pillow or sleep on a firm-as-a-board mattress, the Saatva and Helix have options to boot. Not sure which firmness level is best? Sleep experts generally recommend a medium-firm mattress around a 6 to 8 on a firmness scale of 10 (10 being the firmest). Medium-firm mattresses provide enough support for most back and stomach sleepers, but people who carry a lot of weight or like a very firm mattress should choose something firmer.

Most Saatva mattresses are available in three firmness options: Plush Soft, Luxury Firm and Firm. Helix offers ‘standard’ and ‘luxury’ in its range of models, providing options for every type of berth.

Materials: Foam? Latex? A hybrid that provides the best of both worlds? When searching for a mattress, you will come across these three general types of mattresses, and each has its own set of pros and cons. Your preferred firmness, whether you tend to sleep hot, and whether you share a bed with a partner are all factors that can help you decide which design is best.

Natural latex mattresses usually offer better breathability and temperature control. They also tend to be a bit firmer, with more bounce and less sag. Foam mattresses are known for providing pressure relief and excellent motion isolation. Hybrid designs combine the pressure relief of foam with the responsiveness of latex. Note: Saatva and Helix offer foam, latex and hybrid options.
