The all-foam Zenhaven consists primarily of latex, which is fundamentally durable. The Zenhaven is likewise flippable (the Luxury Plush side feels medium-firm, while the Gentle Company side feels a bit firmer), which may show handy if you’re not sure what you choose or if your needs change gradually. This is not a conventionally soft bed mattress, but it offers a supple cushion, good edge support, and a subtle springiness. Given its inherent sturdiness, the Zenhaven needs to work well for people who weigh more than 200 pounds.
These mattresses were also evaluated in our group tests carried out for Wirecutter’s guides to the finest foam bed mattress and the finest innerspring mattresses. As Wirecutter’s senior personnel author for sleep, I’ve spoken with scores of experts in the mattress industry and in materials science; checked out dozens of bed mattress showrooms, shops, and factories; and pored over the great print on specifications, warranties, and return policies.
Making sense of Saatva Saatva’s portfolio of beds– numerous with a choice of firmness levels and dealing with practically 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). Re Vacuum Seal Foam Mattress
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 haven’t yet done a deep dive into the “natural” claims of Saatva or of other “eco-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 bed mattress companies, Saatva touts such additionals as zoned layers for “optimal spinal column support”; we’re less pleased with those features and more appreciative of Saatva’s responsive customer care and resilient foams and coils.
