Foam Royal Mattress
Smart Comfort. Lasting Value. Built for Life’s Versatile Spaces.
The Foam Royal Mattress is designed to deliver supportive comfort without the high price tag. Whether you’re outfitting a bunk bed, daybed, Murphy Bed, camper, or guest room, this thinner, budget-conscious option gives you more than expected at every layer.
Built with a medium-firm 4″ foam core (ILD 36) for support and topped with a soft quilted comfort layer, it offers gentle pressure relief and reduced motion transfer to help you sleep more soundly. At only 4.75″ tall, it’s compact enough for tight spaces yet durable enough for everyday use.
