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.

Beautyrest Harmony Lux Diamond

Do I need to flip or rotate my mattress?

Beautyrest mattresses are designed to be one-sided and do not need to be flipped. However, you can rotate the mattress 180 degrees (from head to foot) if you wish, but this is not a requirement under the warranty guidelines.

How do I clean my mattress?

To clean your mattress, apply baking soda to the soiled area, let it stand for about 15 minutes, then vacuum. Repeat as needed and air out the product as much as possible. Avoid applying liquids as they can stain the fabric and worsen the soiled area. Using a mattress protector is highly recommended to protect your mattress from stains and spills and to prolong its lifespan.

Can I use an adjustable base with my Beautyrest mattress?

All current Beautyrest mattresses are compatible with adjustable bases. The mattresses are tested for compatibility with Beautyrest branded adjustable bases.
