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.	You can choose from three different operating modes: Manual, Automatic, and Position, which give you total control over the settings. This will give you different comfort levels at each pressure point for maximum support and comfort.
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 smart sensors of this bed read body pressure and make adjustments in real-time as you sleep. No more fiddling with remote controls. Or you can control each pressure point allowing you to get the perfect customized support while you sleep.

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.

Ghost SmartBed

How do I assemble the Ghost Smartbed 3d Matrix?

Setting up the Ghost SmartBed 3D Matrix® is straightforward. You'll receive two boxes: one with the pump and another with the mattress. First, unbox and unroll your mattress to allow it to expand. Then, follow the instructions in the User Guide or Setup Video to connect the pump and air chambers. Lastly, download the GhostBed App and complete the final steps within the app.

Where do I download the Ghost Smartbed App?

The Ghost SmartBed app can be downloaded from the Android or iOS app stores using any personal Android or iOS device. Each side of the bed can be controlled separately by you and your partner using individual apps.

Does the Ghost Smartbed require a WIFI network?

No, the Ghost SmartBed does not require a WiFi network. It comes with its own WiFi chip, allowing for a direct connection if you prefer not to connect it to your home network.
