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 Carbon
How many coils does Harmony Lux have?
The Beautyrest Harmony Lux models all feature the same pocketed coil support unit, which includes 850 coils (in the queen size) and provides zoned support.
What is the Seaqual Fabric Technology?
Seaqual is a collaborative initiative aimed at cleaning our oceans and raising awareness about marine litter. They convert ocean plastics into luxurious, high-quality sustainable fabrics. These fabrics not only feel great but also contribute to cleaner oceans. Each queen-size mattress made using Seaqual fabric helps to eliminate the equivalent of up to 50 water bottles from the ocean.
How do I know which firmness to select when I am mattress shopping?
The choice of mattress firmness is subjective and depends on your personal preferences and problem areas. Stomach sleepers generally benefit from a firmer mattress, while back sleepers find comfort in a firm to medium feel. Side sleepers often prefer a medium or plush mattress with extra pressure relief. These guidelines can assist in narrowing down options, but personalized recommendations based on individual needs can be obtained from the Customer Support team.
