With a cooling cover and a gel-coated memory foam top layer the Nectar Lush helps regulate temperature to stay cool and in a deep sleep. The top memory foam layer helps provide temperature regulation while you sleep. The PCM gel that has been infused into the surface of this component is known to: help draw excess heat away from the body and retain it in the component itself to help cool the sleeping environment to the optimal temperature Release any retained heat from the component back to the body to help heat the sleeping environment to the optimal temperature.
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 Nectar Lush features an innovative memory foam with a higher density than what is found in traditional foam products. The increased density helps provide superior pressure relief for a plush, floaty rest.The top memory foam layer helps provide cushioning for the body at its most sensitive areas, like the pressure points. This is often described as the much-loved, traditional "memory foam" feel: softness, cushion, pressure relief, comfort, etc. The second memory foam layer, or the transition layer, is intended to help provide resistance against the body as you lay down on top of the mattress. If you were to jump onto your mattress, this layer prevents you from feeling the base support layer of foam. The base support layer is intended to provide solid support for the layers above it. It helps give structure and stability for all of the other components to perform as desired.

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

Is Nectar Premier soft or firm?

The Nectar Premier Mattress has a medium firmness level, providing ample support for stomach sleepers.

What is Nectar Premier?

Is the Nectar Premier Mattress Worth It?

The Nectar Premier Mattress, with its high-quality materials and competitive price, is a good value for money. It is particularly suitable for side sleepers over 130 pounds and back sleepers under 130 pounds.
