SOMNIKEN 5" Twin Memory Foam Mattress vs Bedz King 7-Inch Memory Foam Twin Mattress

Both are low-profile twin memory foam mattresses aimed at bunk and trundle beds. The Bedz King adds two inches of thickness, a cool-to-touch cover and titanium-infused foam, and it scores higher on its small rating pool. The SOMNIKEN counters with a removable, machine-washable cover, a fiberglass-free build and a much larger base of ratings. For a kid's first bunk mattress, the SOMNIKEN's washable cover is the more practical pick; for a taller child or an adult guest bed, the Bedz King's extra thickness and motion-damping support layer are worth stepping up to.

• Choose the SOMNIKEN if you want a washable cover, a fiberglass-free build and a mattress backed by more owner ratings for a bunk, trundle or small kid's room.
• Choose the Bedz King if you want a thicker 7-inch profile, a cool-to-touch cover and titanium-infused foam, and you are buying for a bunk, captain's bed or low loft.
