Which California-king mattress topper is best?
Having a California-king mattress offers ample space for sleeping, but to truly enhance your sleep experience, investing in a quality mattress topper is essential. A good topper can provide additional support and comfort, helping you achieve a restful night.
After testing several options, we found the Saatva Mattress Topper stands out for its material versatility and overall comfort.
What to know before you buy a California-king mattress topper
A mattress topper is a thick layer added to your mattress, typically measuring between 1-4 inches in thickness. Its primary purpose is to enhance the comfort and support of your existing bed. You’ll find various firmness levels and materials available, including memory foam, latex, down, and fibrefill.
Thickness
Most mattress toppers range in thickness from 1 to 4 inches. Generally, thicker options provide more support, while thinner ones focus on comfort. Consider your personal preferences when selecting a topper that meets your comfort and support needs.
Certifications
Quality mattress toppers should come with certifications ensuring the materials are free from harmful chemicals. For instance, the CertiPUR-US certification for foam toppers indicates they contain no harmful substances and have low VOC emissions.
If you’re considering down toppers, look for the Responsible Down Standard (RDS), which ensures ethical sourcing and animal welfare.
Firmness
The firmness of your mattress topper is crucial for creating a comfortable sleep surface. If your current mattress is too hard, a softer topper may be beneficial, while a firmer topper can complement a soft mattress for better support.
What to look for in a quality California-king mattress topper
Temperature regulation
Some materials, such as latex and memory foam, can retain heat. To mitigate this, gel-infused memory foam is designed to cool you down, while graphite memory foam promotes natural ventilation for better airflow.
High-density foam
Top-quality memory foam mattress toppers often utilise high-density foam, creating a medium-firm surface that contours to your body, enhancing support and comfort throughout the night.
Limited motion transfer
If you share your bed, a quality mattress topper should minimise motion transfer, ensuring that movements on one side of the bed don’t disturb the other sleeper.
Machine-washable cover
A good mattress topper should have a removable cover for easy cleaning, helping to maintain hygiene and benefiting allergy sufferers.
Customisable options
Many brands are now offering customisation options for thickness, firmness, and materials, allowing you to tailor your mattress topper to your specific sleep needs.
How much you can expect to spend on a California-king mattress topper
Prices for mattress toppers can range from £70 to £1,360, depending on the materials and features. On average, you might spend between £355 and £400.
