Frequently asked questions
What size is a king mattress?
A standard king mattress measures 76 inches wide by 80 inches long, providing ample space for two sleepers. It is often called an Eastern King, while a California king is longer but narrower.
Do you need a special box spring for a king mattress?
Many modern king mattresses, especially hybrids and memory foam, are designed for use on a foundation or platform bed rather than a traditional box spring. Always check the manufacturer's warranty requirements.
How long do king mattresses typically last?
The lifespan of a king mattress varies by material and quality. Innerspring and hybrid models often last 7-10 years, while all-foam may show sag in 5-8 years. Look for certifications like CertiPUR-US for foam quality.
What is the best firmness for a king mattress?
The ideal firmness depends on your sleeping position. Side sleepers usually prefer medium (4-6 on firmness scale), stomach sleepers need firmer (6-8), and back sleepers often do well with medium-firm (5-7).
Are king mattresses compatible with adjustable bases?
Most modern king mattresses are designed to work with adjustable bases, especially those made of memory foam or hybrid construction. Check the flex rating and warranty to ensure compatibility.
