| 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. | Venus FIT Layer's Advanced Sleep Technology uses a special blend of far infrared (FIR) minerals that absorb your body heat as you sleep and reflect it back to you. When you are lying down, use your body's energy to mimic the effects of heat therapy. This improves blood flow and circulation, your body is able to better control its temperature, so overheating becomes a thing of the past. |
| 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. | With four layers of support, you get a plush feeling while still receiving all the spinal support you need. Gel memory foam is an incredible material to sleep on, but we've enhanced it by infusing it with our unique blend of far infrared minerals. Your body will benefit from an even distribution from head to toe as 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.
Venus Williams Legend
Who should get the Venus Williams mattress?
The Venus Williams Legend mattress is suitable for anyone who wants a good night's sleep. It features advanced sleep technology that is ideal for athletes who need a recovery boost, but the health benefits of FIR technology can help all types of sleepers. Over a few weeks, you'll find that you're waking up with more energy and ready to face the day, regardless of what's on your schedule.
Do the Venus Williams mattresses come with a sleep trial?
Absolutely! In fact, we're proud to offer one of the longest mattress sleep trials out there: a whopping 101 nights. The trial applies to all GhostBed mattresses, and you'll get 3+ months to lounge, nap, snooze & snuggle to decide. Learn more about how our sleep trial works here.
Do the Venus Williams mattresses have a warranty?
Yes, they do. Your Venus Williams mattress comes with an industry-leading 25-year warranty, provided you have proof of purchase from the official GhostBed website or an authorized retailer.
