Frequently asked questions
What is a full extra long mattress?
A full extra long mattress measures 54 inches wide by 80 inches long, providing extra length for taller individuals. It's less common than twin XL but fits full XL bed frames.
Who should buy a full XL mattress?
Single sleepers over 6 feet tall who need more legroom often choose full XL. It's also suitable for guest rooms where space is limited but length is important.
What certifications should I look for?
Look for CertiPUR-US or OEKO-TEX Standard 100 certifications to ensure no harmful chemicals. GOLS is best for organic latex mattresses.
How long is the trial period for these mattresses?
Most offer 100-365 nights. Longer trials like Nectar's 365 allow thorough testing. Ensure a return policy is available if needed.
Can I use standard full sheets on a full XL?
Full XL requires specific sheets due to its longer length. Standard full sheets will be too short. Many retailers sell full XL sheets separately.
The verdict
For overall value and comfort, the Nectar Memory Foam Mattress wins. Side sleepers should choose Helix Midnight Luxe, while luxury seekers prefer Saatva Classic. Budget buyers can't go wrong with Zinus Green Tea.
