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.	Ventilation is the key to sleeping just right - not too hot, and not too cold. Purple achieves the ultimate sleep comfortability by combining a totally new material with a totally unique design. Purple remains temperature-neutral so you don't sleep hot and sweaty at night Purple's column design allows air to flow freely, preventing moisture trapping, extending the life of the mattress, and providing cleaner, more comfortable sleep. Thanks to the free air flow design and patented polymer materials, Purple naturally sleeps much cooler than memory foam, latex, and other mattress technology.
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.	A revolutionary mattress designed for just about everyone. It's designed to not only help you get better sleep, but to soothe joints, release pressure on the hips and shoulders, and support the neck and back. It's designed to make bedtime the highlight of your day! The Hyper-Elastic Polymer Purple is a pressure-releasing material. This material is organized in a grid formation, which creates walls that can support or fold, depending on how much pressure it receives. It's durable enough to last decades so you won't develop a body impression. And it buckles under specific pressure, which provides excellent motion isolation so you don't feel someone else move in the bed.

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.

Purple

Why do people like Purple mattresses?

The Purple mattress is favored for its ease of movement compared to many memory foam mattresses. The Purple Grid is both conforming and responsive, allowing for more movement than highly conforming memory foam.

Do Purple mattresses need special sheets?

Regular sheets can be used with a Purple bed, but they must be of the right type. The best sheet materials for a Purple mattress are bamboo viscose and cotton, provided they promote breathability and have the ability to stretch.

What body type is best for Purple mattress?

The Purple mattress is an excellent choice for back and stomach sleepers. However, for heavier back or stomach sleepers, the Original Purple bed may not be the best option.
