| 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. | A Truly Comfortable Organic Mattress. Everything in the Happsy mattress was designed for comfort and breathability. Natural fibers like organic cotton and wool just feel better than the polyurethanes and polyesters of the world. Plus, you wont be exposing yourself to all those chemicals. Now that's what we call organic comfort. Air channels carved into the latex help keep you cool and comfortable. Similar to the way maple syrup is made, the milky sap from the Hevea Brasiliensis tree is tapped and baked into a luxurious organic foam (like a giant waffle)! Yes, you read correctly - this foam is made from the renewable sap of trees. Certified to the Global Organic Latex Standard (GOLS). Do you find yourself sweating in your sleep despite "sleep cool" claims from your existing mattress brand? Foam is an insulator that traps heat - simple as that. Happsy's breathable coil system and moisture wicking wool gives heat somewhere to go, keeping you cool and comfortable all night long. |
| 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. | Unlike a firm piece of foam where every point is "stuck" in place, coils have a far broader range of movement, conforming to any sleeping position. Pocketed springs, in particular, uniformly cradle whatever's on them while drastically reducing motion transfer. After all, the most common cause of sleep disturbance is your sleep partner! Best of all, these coils are really breathable, giving heat somewhere to go. Perimeter coils zoned firmer for edge support. The Happsy mattress features a full 2" of pure organic latex, perfect for that sought after feeling of floating pressure point relief. |

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.
Happsy Organic
How firm is the Happsy Mattress?
The firmness of the Happsy mattress depends on whether you add the topper. Without the topper, it is considered "medium-firm." With the topper, it becomes slightly softer with additional cushioning.
Can your mattresses be used with a flex bed frame?
Yes, the hybrid design of the Happsy mattress, featuring individually encased springs, is compatible with flex/adjustable bases.
Are the coils made of metal?
Yes, the coils in the Happsy mattress are made of steel and are approved by GOTS.
