Cover	Soft and Comfy Cover: Soft to touch and breathable to keep you cool and comfortable.	Quilted top panel woven with our signature A. This is a Euro top mattress with two layers of high-performance memory foam underneath its plush quilted surface which makes for a supreme sleep experience.
Machine-washable cover	No	No

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.	Stay asleep with individually-wrapped coils which help minimize motion transfer. Cooling graphite and copper gel layer absorbs and transfers heat away from the body.
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.	Two-sided edge support with Reinforced Quantum Edge - use the whole sleeping surface and easily get in and out of the bed. Energex foam provides pressure relief over a wide range of temperature.

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.

Allswell Supreme

How thick is Allswell Supreme?

The Allswell Supreme mattress has a thickness of 14 inches.

What is the weight limit for the Allswell Supreme?

The Allswell Supreme mattress can comfortably support individuals who weigh up to 230 pounds.
