Frequently asked questions
What is a super king mattress?
A super king mattress is typically 6 feet wide and 6 feet 6 inches long (72" x 78"), offering ample space for couples. It's larger than a standard king, providing extra legroom and comfort.
Are cheap super king mattresses durable?
Yes, many budget-friendly options use high-density foams and CertiPUR-US certified materials for durability. However, cheaper mattresses may have shorter lifespans compared to premium models, often lasting 5-7 years with proper care.
How do I choose the right firmness?
Consider your sleeping position: side sleepers prefer soft to medium, back sleepers medium, and stomach sleepers firm. Trial periods let you test at home. Our picks include various firmness levels to match different preferences.
Do cheap mattresses sleep hot?
Not necessarily; many budget mattresses now include gel-infused foams or breathable covers to regulate temperature. Look for cooling features like those in the Casper Original or Zinus Green Tea if you sleep warm.
What certifications should I look for?
Look for CertiPUR-US (no harmful chemicals) and OEKO-TEX Standard 100 (no harmful substances). These ensure the mattress is safe for you and the environment. All our picks meet these standards.
