Frequently asked questions
What is a California king innerspring mattress?
A California king is 72 inches wide and 84 inches long (4 inches longer than a standard king). An innerspring uses a coil support core for bounce and support, often combined with foam or latex layers for comfort.
How do I choose the right firmness for a California king innerspring?
Firmness depends on sleeping position: side sleepers generally need softer (medium or plush) to relieve pressure, while back/stomach sleepers prefer medium-firm to firm. Consider your weight, heavier individuals often need firmer support.
Are innerspring mattresses good for back pain?
Many innerspring hybrids with zoned support can help with back pain by promoting spinal alignment. Owners often report relief with supportive coils and comfort layers. Always check for good edge support and motion isolation.
How long does a California king innerspring mattress last?
Quality innerspring mattresses last 7-10 years with proper care. Coil gauge (lower number = thicker wire) and construction quality affect durability. Budget models may sag sooner. Look for warranties of at least 10 years.
Do I need a special box spring for a California king innerspring?
Most innerspring mattresses require a supportive foundation, such as a box spring or slatted base (slats no more than 3 inches apart). Some brands sell compatible foundations. Always follow manufacturer guidelines to avoid voiding the warranty.
