FAQs

Puffy Diamond

What does hybrid mattress mean?

A hybrid mattress merges the supportive features of an innerspring mattress with the softness of memory foam. The Puffy Diamond Hybrid enhances this by integrating pocketed coils with high-quality materials like alpaca wool, premium latex, and multiple layers of refined memory foams.

How often should you change your mattress?

Typically, mattresses last 7-8 years, but luxury ones like Puffy can go up to 10 years. If your mattress is over 5 years old or isn't comfortable, consider getting a new one. Puffy offers a 101-night trial and a lifetime warranty for assured comfort and reliability.

What is the weight capacity of the Puffy mattresses?

Puffy mattresses cater to diverse sleepers and weights. The twin to full-size mattresses support up to 350 lbs. The larger sizes like queen, king, and California king can hold 350 lbs on each side.

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.
