Are you tossing and turning on a bed that’s too small, or maybe your partner is hogging the covers? A full size mattress, also known as a double bed, might be the perfect middle ground for more space without blowing your budget. It gives you 15 inches more width than a twin, so you can finally stretch out.
But here’s the thing: not all full mattresses are the same. You need to pick the right firmness, material, and cooling features to actually get good sleep. In 2026, the market is full of options from memory foam to hybrid to innerspring, so let’s cut through the noise.
What to Know About a Full Size Mattress in 2026 (Double Bed Basics)
A full size mattress measures 54 inches wide by 75 inches long. That’s enough room for a single adult who wants extra space, or for a couple who don’t mind cozy sleeping. Brands like Serta, IKEA, Lucid, Nectar Sleep, Zinus, Ashley, Purple, and Stearns & Foster all offer models in this size, with prices from $300 to $2,500.
The three main types are memory foam, hybrid, and innerspring. Memory foam molds to your body and relieves pressure, but newer versions include cooling gel or breathable covers to stop overheating. Hybrid mattresses combine foam comfort layers with pocketed coils for support and bounce. Innerspring mattresses are the classic choice with a bouncy feel and good airflow.
Firmness matters too. A medium firm full mattress works for most sleepers, while plush is softer for side sleepers and firm is better for stomach sleepers. If you share the bed, look for motion isolation to avoid feeling your partner move. Extended trial periods, like Nectar’s 365-night trial, let you test the mattress at home.
