Frequently asked questions
Can I use any 15-inch mattress in a Murphy bed?
Most 15-inch mattresses work in standard Murphy beds, but check manufacturer guidelines for weight and folding compatibility. Certifications like CertiPUR-US ensure quality and durability for repeated folding.
What firmness is best for a Murphy bed mattress?
Medium-firm is often recommended (5-7/10) as it provides support without being too rigid. Side sleepers may prefer slightly softer, while stomach sleepers need firmer options to prevent sagging.
Do Murphy bed mattresses need special construction?
Look for mattresses with reinforced edges and flexible cores to withstand folding. Many owners find that all-foam or hybrid mattresses with good flexibility work best.
How long do 15-inch mattresses last in a Murphy bed?
High-quality mattresses with CertiPUR-US certification can last 5-7 years. Aggregated owner reports suggest that hybrids may have slightly longer lifespans due to coil support.
Should I buy a mattress with a longer trial period for a Murphy bed?
Yes, a trial period of 100 nights or more allows you to test compatibility with your Murphy bed. Owners recommend using the full trial to ensure no sagging or fit issues.
