Frequently asked questions
What size blanket fits a California King?
You should look for a blanket labeled 'California King' which typically measures around 108" x 96" or larger. This ensures enough drop on the sides and foot of the bed. Some oversized blankets measure 110" x 96".
Are California King blankets different from regular King blankets?
Yes, California King beds are longer (72" x 84") than standard King (76" x 80"), so blankets need extra length. A regular King blanket may be too short, leaving the foot of the bed uncovered.
What materials are best for a California King blanket?
Cotton and bamboo are breathable and great for warm sleepers. Down and down alternative provide warmth without weight. Microfiber is affordable and soft but may not be as durable. Choose based on your climate and sleeping temperature preferences.
How do I wash a California King blanket?
Always check the care label. Most synthetic blankets are machine washable on gentle cycle with cold water, then tumble dry low. Down comforters may require professional cleaning. Using a front-loading washer is recommended for king-sized blankets.
What certifications should I look for?
Look for OEKO-TEX or STANDARD 100 by OEKO-TEX certification, which means the blanket is tested for harmful substances. CertiPUR-US is common for foam products but not blanket fillings. These ensure safety and quality.
