The all-foam Zenhaven consists mostly of latex, which is inherently long lasting. The Zenhaven is also flippable (the High-end Plush side feels medium-firm, while the Gentle Firm side feels a bit firmer), which may prove handy if you’re not exactly sure what you prefer or if your needs alter in time. This is not a conventionally cushy mattress, but it uses a flexible cushion, excellent edge support, and a subtle springiness. Given its natural resilience, the Zenhaven must 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 bed mattress for numerous weeks in my own home. These mattresses were also examined in our group tests performed for Wirecutter’s guides to the finest foam mattresses and the best innerspring bed mattress. As Wirecutter’s senior staff writer for sleep, I’ve spoken with scores of specialists in the bed mattress industry and in materials science; visited dozens of mattress display rooms, stores, and factories; and read the fine print on specifications, guarantees, and return policies. Most recently, monitoring editor Courtney Schley assessed the Saatva Latex Hybrid in her home for a number of weeks.
Understanding Saatva Saatva’s portfolio of beds– many with a choice of firmness levels and catering to practically every convenience choice– includes: Saatva Classic ( innerspring).
Loom & Leaf ( all foam).
Zenhaven ( all latex).
Saatva Latex Hybrid ( latex with coils).
Solaire ( a bed with adjustable air chambers). Purple Mattress Unpacking
Saatva HD ( a latex-coil hybrid developed 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” brands. However we do know that the company utilizes thistle pulp or natural wool as a flame retardant (rather than fiberglass or chemicals) and only natural cotton (instead of artificial blends) in its covers. As do other online bed mattress business, Saatva promotes such extras as zoned layers for “optimum spinal column assistance”; we’re less impressed with those features and more appreciative of Saatva’s responsive customer care and resilient foams and coils.
