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.	Nectar Premier Copper delivers dream-state comfort with an extra inch of foam. So you doze off dreamily on a taller, denser sleep surface. With such minimal motion transfer, you can do a little happy dance without waking your partner. Phase-changing material dynamically adapts to your sleep temp, while 4 inches of cushy, pressure-relieving gel memory foam cuddles every curve and joint. So you zonk out in a temperature-responsive oasis.
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.	Stay-Stable Base Layer. This sturdy 9-inch bottom layer of foam ensures the comfort and support layers above it perform at their tip-top best. Mo’ base, mo’ support. Get ultimate relief at the pressure points beneath your shoulders, hips and legs for proper spinal alignment. A taller base gives Nectar Premier Copper’s support layer what it needs to deliver your ultimate relief. Because truly relaxed muscles are the key to deeper dreaming.

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.

Nectar Premier Copper

Is the Nectar Copper good for stomach sleepers?

The Nectar Premier Copper Mattress may not be the best choice for stomach sleepers, unless they weigh less than 130 pounds. A firmer mattress is generally better for stomach sleepers as it helps keep the spine even.

Is the Nectar Premier Copper a good mattress?

Yes, the Nectar Premier Copper is a high-quality mattress made with durable foams. It's particularly suitable for back sleepers, side sleepers, and those who tend to sleep hot and want a foam mattress that stays cool.

Can you flip the Nectar Premier Copper mattress?.

No, the Nectar Premier Copper mattress is not designed to be flipped. If flipped, you would be sleeping on the firm support layer instead of the softer comfort layers.
