Buying Guide
Key considerations when choosing a sofa bed mattress:
- Thickness and support: Thicker models (3.5–4.5 inches) tend to offer better support for longer sleep sessions, especially for heavier users or side sleepers.
- Cooling comfort: Gel-infused memory foam helps regulate temperature and reduces overheating during the night.
- Size compatibility: Verify sofa bed measurements (Queen, Full, or others) to ensure a snug fit without gaps or excess overhang.
- Durability and safety: Look for CertiPUR-US and OEKO-TEX certifications for low emissions and durable materials.
- Portability and storage: Foldable or vacuum-packed designs save space and simplify transport for travel or guest storage.
- Cover and maintenance: Removable, washable covers improve hygiene and ease cleaning, especially for guest use.
