Construction & materials

	Siena Memory Foam	Avocado Vegan
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.	Rather than using wool, our Vegan Mattress uses 400 grams per square foot of 100% GOTS organic certified certified cotton batting. Avocado mattresses feature 100% GOLS organic certified latex rubber foam, made from sustainably harvested sources. It's an eco-conscious, high-performance material, offering resilience, durability, and temperature control that far exceeds synthetic, blended or petroleum-based polyurethane foams
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 Vegan Mattress is GREENGUARD Gold Certified - and made with natural and organic materials, including 100% GOLS organic certified latex from tree-tapped and sustainable sources and GOTS organic certified cotton. Our non-toxic vegan bed combines the finest natural cushioning with an internal, zoned, pressure-point support system for proper back support and extended durability. No wool is used anywhere in the mattress. The Avocado Vegan 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 5 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 Vegan

Are Organic Mattresses Worth The Money?

Avocado mattresses are handcrafted from the finest natural, organic ingredients for superior durability, sustainability, and comfort. Their non-toxic, certified organic mattresses are also safer for you, your family, and the planet.

Are Organic Mattresses Necessary?

Avocado mattresses use only natural and organic materials to deliver luxurious sleep that is better for your long-term health and the health of the planet.

How is the Luxury Organic Mattress shipped?

For larger mattresses, like the Luxury Organic Mattress, optional In-Home Delivery & Setup Services are recommended due to their weight.
