Watch the video below to see how the Zenhaven Mattress performed when put to the test in the Sleep Foundation Lab.
The Zenhaven has four layers of latex in total, made up of a comfort layer and a support layer for each side. All the latex is 100% natural Talalay latex, which is lighter and airier than Dunlop latex. Both sides have an organic cotton cover with natural wool padding.
We found the Gentle Firm side to equate to a 7 out of 10 on our firmness scale, or “Firm.” The Luxury Plush side is closer to a 4 out of 10, or “Medium Soft.” Since the Zenhaven is solid latex and therefore quite heavy, Saatva will send a team to flip the mattress if you decide you prefer the other side after all.
An organic cotton cover provides a soft and breathable surface for the Zenhaven mattress. The cover is coated with Guardin® antimicrobial treatment. Under the cotton there is a thin layer of New Zealand wool, which wicks away moisture from the sleeper and provides a natural fire barrier.
The firm side has a comfort layer consisting of 1.5 inches of N2 Talalay latex. This layer has an indentation load deflection (ILD) of 20-24, which is relatively firm. Sleepers will mostly sleep on top of the mattress. The medium soft side comfort layer consists of 1.5 inches of N1 Talalay latex with an ILD of 14-19, which is quite plush and allows closer conforming.
Both comfort layers are divided into 5 zones, using different-sized pincore holes to provide a firmer surface under the torso and shoulders. The pincore holes also add breathability to the mattress, maintaining a cool sleep surface throughout the night.
Under the comfort layer, the firm side of the Zenhaven is supported by 3 inches of N4 Talalay latex with an ILD of 30-34. The medium soft side has 3 inches of N3 Talalay latex, which has an ILD of 25-29.
Together, these support layers form a firm core that prevents sleepers from sinking in too far and keeps the spine aligned.
In total, the Zenhaven has four layers of latex. Each side has 1.5 inches of comfort layers plus a 3-inch support core.

The Zenhaven is priced at $2,399 for a queen, which is quite reasonable for an all-latex mattress.
Natural latex is expensive to produce but it usually outlasts other mattress types, which makes it a worthwhile investment. Talalay latex in particular costs more to produce than Dunlop latex, but is prized for its enhanced breathability and lighter, more uniform feel.
Each Zenhaven mattress is delivered with complimentary White Glove delivery, and Saatva offers optional old mattress removal at no extra fee. Most online mattress companies charge at least $100 for these options.

Zenhaven – Medium Soft Side
The Zenhaven’s medium soft side offers closer conforming that works well to relieve pressure points in side sleepers, especially those who weigh less than 130 pounds. Heavier side sleepers may find that their hips sink in a little too far.
Despite the zoned comfort layers that help support the lumbar area, the medium soft side of the Zenhaven is somewhat too soft for most back sleepers.
Typically, back sleepers are most comfortable on a mattress that falls between 5 and 7 on the firmness scale, and the Zenhaven falls at a 4. Those who weigh less than 130 pounds will be all right, but those who weigh more than 130 pounds may find the mattress doesn’t provide sufficient support to maintain spinal alignment.
Stomach sleepers require a firmer surface to keep the hips from sinking, as this is where most people carry the bulk of their weight. The medium soft side of the Zenhaven is a tad too plush and may fail to keep the spine aligned in stomach sleepers.
Those who weigh less than 130 pounds don’t sink in as far, and as a result, these stomach sleepers should find the medium soft side fairly comfortable.
|Under 130 lbs.||130-230 lbs.||Above 230 lbs.|
Zenhaven – Firm Side
The harder surface of the Zenhaven’s firm side may cause pressure points in some side sleepers, particularly those who weigh less than 130 pounds.
Sleepers over 130 pounds exert more pressure on the mattress and will get more of the pressure-relieving benefits of the zoned comfort layer. For these sleepers, the Zenhaven should be fairly comfortable when sleeping on the side.
The firm surface and zoned comfort layers of the Zenhaven cradle back sleepers, providing an even balance of support and pressure relief to keep the spine aligned. Back sleepers who weigh at least 130 pounds should find the mattress very comfortable.
At 7 out of 10 on the firmness scale, the Zenhaven’s firm side is more than firm enough to keep the spine on an even plane. This is true of most stomach sleepers, especially those who weigh 130 pounds or more.
|Under 130 lbs.||130-230 lbs.||Above 230 lbs.|
The Zenhaven ships with free White Glove delivery to the contiguous U.S. and some locations in Canada. Delivery times vary between 7-18 days depending on location.
Saatva does not currently ship mattresses directly to Hawaii or Alaska. That being said, they may be able to coordinate a delivery to those states with a third party.
The mattress is only available for purchase on Saatva.com. Saatva recently opened a viewing room in New York City where customers can try out the mattress.
All Zenhaven mattresses are shipped with free White Glove delivery through a third-party delivery service. The mattress is not compressed for shipping. The delivery team will set up the mattress inside your home and remove your old mattress if you select this free option at checkout.
Saatva asks you to select a preferred firmness level at the time of ordering, so the delivery team can set it up on the right side. Because the mattress is quite heavy, you can contact Saatva who will send a team to flip the mattress free of charge if you decide you prefer the other side.
The day before delivery, the provider will reach out to schedule a 4-hour delivery window. If the driver is late, customers can choose to reschedule the delivery or cancel the order. If there is no adult home during the delivery window, the mattress will be sent back. In this case, you can reschedule the delivery or cancel it, but in both instances, you will be charged a $99 transportation fee. If the mattress doesn’t fit into the room you have specified, it will be sent back and you will be responsible for the $99 transportation fee.
If the mattress arrives damaged, you can refuse it and receive a full refund, or get a new one delivered. If you need to sleep on it that night you can accept it while you wait for the new one, as long as this is noted on the driver’s delivery slip. If Saatva makes a mistake with the order you can also keep the mattress while you wait for the correct one to arrive.
White Glove delivery service is included with all Zenhaven mattress orders. Old mattress removal is available at no extra charge for customers who select this option at checkout.
The Zenhaven mattress comes with a 180-night sleep trial. Customers who decide to return the mattress during this time will receive a full refund minus a $99 transportation fee.
Saatva stands by the Zenhaven mattress with a 20-year non-prorated warranty against workmanship and material defects for the original purchaser.
For the first two years, Saatva will replace a defective mattress with a brand-new one at no cost to the customer. After that, Saatva will repair and re-cover a defective mattress for a $99 transportation fee each way.
If customers wish, they can opt for the Fairness Replacement Option. In this case, they get to keep their defective mattress and buy a new one at a reduced rate. This rate shall be 40% of the original purchase price in years 3-5, 60% of the original purchase price in years 6-10, and 80% of the original purchase price in years 11-15, plus a delivery fee of $99. This option can be used a maximum of one time per customer.
The warranty covers body impressions at least 3/4 inch deep. To qualify for the warranty, the mattress must be used on a uniform surface. Platform beds should have a solid surface placed over them, and queen and king mattresses must be supported by at least 5 or 6 legs including a vertical center support. Adjustable bases are also acceptable.
Burned, abused, or otherwise damaged mattresses shall have their warranty voided.
