The all-foam Zenhaven consists mostly of latex, which is inherently resilient. The Zenhaven is also flippable (the High-end Plush side feels medium-firm, while the Mild Firm side feels a bit firmer), which may show helpful if you’re not exactly sure what you prefer or if your needs change in time. This is not a traditionally soft mattress, however it provides a supple cushion, great edge support, and a subtle springiness. Given its inherent durability, the Zenhaven needs to work well for people who weigh more than 200 pounds.
For this review, I slept on the Saatva Classic, the Loom & Leaf, and the Zenhaven mattresses for numerous weeks in my own home. These mattresses were also evaluated in our group tests performed for Wirecutter’s guides to the finest foam mattresses and the finest innerspring bed mattress. As Wirecutter’s senior personnel writer for sleep, I have actually talked to ratings of specialists in the bed mattress market and in materials science; gone to lots of mattress showrooms, stores, and factories; and read the small print on requirements, warranties, and return policies. Most recently, supervising editor Courtney Schley evaluated the Saatva Latex Hybrid in her house for a number of weeks.
Making sense of Saatva Saatva’s portfolio of beds– lots of with a choice of firmness levels and accommodating nearly every convenience preference– consists of: Saatva Classic ( innerspring).
Loom & Leaf ( all foam).
Zenhaven ( all latex).
Saatva Latex Hybrid ( latex with coils).
Solaire ( a bed with adjustable air chambers). Casper 4 Layer Premium Mattress
Saatva HD ( a latex-coil hybrid created for sleepers who weigh 300 to 500 pounds).
Saatva Youth ( a foam-coil hybrid for kids ages 3 through 12).
We have not yet done a deep dive into the “natural” claims of Saatva or of other “environmentally friendly” brand names. However we do know that the company uses thistle pulp or organic wool as a flame retardant (rather than chemicals or fiberglass) and only natural cotton (instead of synthetic blends) in its covers. As do other online mattress business, Saatva promotes such additionals as zoned layers for “optimal spine assistance”; we’re less amazed with those functions and more appreciative of Saatva’s responsive client service and resilient foams and coils.
