| Layers | Responsive Memory Foam, Body Supporting Layer, Foundational Foam | Organic Cotton Ticking, JOMA® New Zealand Wool, Natural Hydrated Silica Fire Barrier, Leggett & Platt Quantum Edge® Elite Combi-Zone®, Soft Natural Dunlop Latex |
| Cover | Soft and Comfy Cover: Soft to touch and breathable to keep you cool and comfortable. | For a luxurious and premium finish, we use a breathable organic cotton / poly-blend 4-way stretch-knit (rather than a traditional weave) in a soft, natural color, and GOTS-certified by our supplier. Sourced from the United States, this durable textile is button-tufted by hand with wool yarn rosettes, which secure the cotton ticking and internal mattress layers firmly in place without the use of chemical adhesives. We also use hand-stitched tape edges (double stitched) and heavy-duty upholstered handles to complete the package. |
| Machine-washable cover | No | No |
| Ergonomic handles | No | Yes |
| 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. | Wool does what other materials can not - it wicks away moisture, stays fresh, and acts as a natural fire barrier. It's also naturally anti-microbial, resistant to dust mites, and offers natural temperature control (to complement our natural latex). Our Joma New Zealand Wool's quality is some of the best in the world. |
| 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. | The Avocado Green Mattress is GREENGUARD Gold Certified - and made with natural and organic materials, including 100% natural Dunlop latex from tree-tapped and sustainable sources; OEKO-TEK Standard 100 certified natural New Zealand wool; and GOTS certified organic cotton. Our non-toxic green bed combines the finest natural cushioning with an internal, zoned, pressure-point support system for proper back support and extended durability. We even make a new Vegan Mattress made without wool. The Avocado Green Mattress features an 8-inch support unit comprised of 756 - 1,414 individually-tuned support coils to ensure proper spinal alignment and balance. These fabric-encased innersprings (made from recycled steel) are arranged in 3 distinct zones with a reinforced perimeter to float independently and reduce motion transfer. This premium, highly durable system allows for optimal and individualized ergonomic and joint support, while at the same time, better contouring to your body shape and evenly distributing weight. Better still, the reinforced perimeter provides critical edge support to eliminate the "roll-off" feeling near the edge. |

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.
Avocado Green
How Are the Layers of Your Avocado Green Mattress Topper Constructed?
The Avocado Green Organic Latex Mattress Topper, which is GREENGUARD Gold Certified®, is made up of 2 inches of GOLS organic certified Dunlop latex. It's covered with organic cotton ticking and organic wool (or organic cotton for the vegan option), and is available in plush or firm options.
Can I Use an Electric Heating Mattress Pad?
Yes, you can use a heating pad with your Avocado Mattress at a low to moderate setting. However, prolonged and repeated use may cause discoloration of the exterior ticking, which is not covered by the warranty. For optimal warmth, it's recommended to use high-quality natural and organic bedding instead of an electric mattress pad.
How Bouncy Is Your Mattress?
Avocado mattresses offer a light bounce and limited motion transfer, making them ideal for couples and active sleepers. The mattresses are responsive yet offer excellent motion control, stability, and flexibility due to their premium 100% GOLS-certified organic latex.
