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.
Purple Hybrid Premier (4" Grid)
How thick is the Purple Hybrid Premier 4 mattress?
The Purple Hybrid Premier 4 mattress, the priciest among the Purple hybrid beds, has a thickness of 13 inches. It offers a medium to medium-firm feel and is suitable for all sleeping positions.
Is Purple 4 good for side sleepers?
Yes, the Purple 4 is suitable for side sleepers. Its thickest top layer provides an immersive experience with the pressure-relieving capabilities of Hyper-Elastic Polymer, making it one of the best mattresses for side sleepers.
Can I return my mattress if Iโm not happy with it?
Yes, Purple offers free returns within 100 nights if you donโt love your mattress. However, they require you to sleep on it for a minimum of 21 nights before initiating a return or exchange. If you're still not satisfied after this period, you can contact their Care Team to schedule a pickup. Once the mattress has been picked up and they receive proof of receipt, they will initiate a full refund.
