Frequently asked questions
What is a super wide king mattress?
A super wide king, also called a Wyoming or Alaskan king, measures 76 inches wide by 80 inches long. That's 6 feet 4 inches by 6 feet 8 inches, offering the same length as a California king but wider.
What certifications should I look for?
Look for CertiPUR-US, which ensures foams are free of ozone depleters and heavy metals, and OEKO-TEX Standard 100, which screens for harmful chemicals. Both indicate healthier indoor air quality.
How do I choose firmness for a king bed?
Consider your primary sleeping position: side sleepers usually prefer medium-plush, back sleepers medium-firm, and stomach sleepers firm. For couples, a medium-firm (6-7 out of 10) often works best.
Do super wide king mattresses fit standard frames?
No, standard king frames measure 76×80 inches, but not all frames support the extra width. Always check frame dimensions and weight capacity, as super king mattresses can be heavier.
What's the best trial period for a king mattress?
We recommend at least 100 nights to adjust. Saatva and Nectar offer 365 nights, which allows for seasonal changes and thorough testing. Ensure the brand has a solid return policy.
The verdict
The Saatva Classic is our overall winner for its durable construction, eco-friendly certifications, and three firmness options. For hot sleepers, the Nectar Premier Copper excels in cooling, while the DreamCloud Premier Rest is the best choice for side sleepers needing pressure relief.
