Comfort	Siena means comfort. Comfort that helps you forget about the worries of the day. Comfort that tells your body, “relax, it’s time to recharge”. Comfort that helps you enjoy a long, deep, and soul nourishing sleep.	Zenhaven's American-made Talalay latex offers a range of health benefits. It's naturally hypoallergenic and resistant to mold, microbes and dust mites. It contains no volatile organic compounds or other harmful substances found in chemical-based bed foams. And it has a uniquely resilient feel that elevates and conforms to your body for perfect support, total comfort, and a truly restorative night's sleep. Latex has an open cell structure that allows air to circulate freely, countering body heat and providing cool, comfortable sleep. This natural air flow gives you a mattress that's seven times more breathable than other types of latex.
Support	Some people love super soft mattresses. Some people love a rock hard one. Most people are somewhere in the middle. That’s why the Siena is a medium firm mattress, comfortable to sleep on, but also firm enough to correctly support your body.	By varying the size and distribution of the "pinholes" formed during the Talalay process, we created a seamless mattress layer with 5 distinct zones of density, providing Zenhaven with firmer support beneath the torso and shoulders and more subtle support elsewhere. The result is pressure-free support and better spinal alignment. Natural latex is the best-kept secret in sleep, and once you have experienced it, nothing else will do. It instantly responds to every curve of your body for pressure-free support and incomparable comfort on both traditional and adjustable bases. A Zenhaven exclusive, our Talalay latex comfort layers feature a proprietary 5-zone design that gives you firmer support where you need it for the ultimate in comfort and spinal alignment.

FAQs

Siena Memory Foam

What are Siena mattresses made of?

The Siena Memory Foam Mattress is made with a tri-layer design that includes gel-infused memory foam and two different types of polyfoam. The foam used in the mattress is CertiPUR-US certified, meaning it's free from harmful chemicals and additives.

Can you flip the Siena mattress?

The Siena mattress is not designed to be flipped. It has a high-density base foam layer at the bottom, and flipping it would compromise its pressure-relieving properties.

How long will the Siena mattress last?

The Siena mattress, being a budget mattress, is not made with as many high-quality materials and is therefore expected to last about five years. This is approximately half the lifespan of a typical mattress.

Zenhaven

How much does zenhaven weigh?

The Zenhaven mattress is dense, weighing in at about 120 pounds. It is constructed with two premium latex cores and is flippable.

How firm is Zenhaven?

The Zenhaven's firm side is rated 7 out of 10 on the firmness scale, providing enough firmness to keep the spine on an even plane for most stomach sleepers, especially those who weigh 130 pounds or more.

What does Zenhaven feel like?

The Zenhaven mattress has a spongy/responsive feel. It provides pressure relief, but more than anything it's just a highly responsive bed.
