Frequently asked questions
What size is a double bed?
A double bed (also called full) measures 54 inches wide by 75 inches long. It's best for single sleepers who want extra space or two people who don't mind cozy quarters.
What is the best mattress firmness for side sleepers?
Side sleepers typically need a medium to medium-soft mattress to relieve pressure on shoulders and hips. A firm surface can cause discomfort and misalignment.
How long does it take to break in a new mattress?
Most mattresses have a break-in period of 30 to 60 days. During this time, the materials adjust to your body, and comfort may improve. Many trials last 100 nights or more.
Are cooling mattresses worth it?
If you sleep hot, cooling features like gel infusions, breathable covers, or coil springs can help regulate temperature. Owners of cooling mattresses often report better sleep quality.
What certifications should I look for?
Look for CertiPUR-US for foam safety and emissions, and OEKO-TEX for fabric safety. These ensure low VOCs and absence of harmful chemicals.
The verdict
The Nectar Premier Copper wins as the best overall double mattress due to its balanced comfort and cooling. For those who prioritize luxury and eco-friendliness, the Saatva Classic is a top choice. Budget buyers should consider the Zinus Green Tea for its unbeatable value.
