Imperius Mattress Support – Wooden Bunkie Board for Queen Bed (60x48), Foldable Under Mattress

Low-profile, dependable mattress support

The Imperius Mattress Support is a wooden bunkie board designed to sit between your mattress and its foundation. It delivers mid-mattress reinforcement to help maintain a comfortable surface and can help preserve an aging mattress by reducing center sag. The compact, low-profile form keeps the bed looking sleek while adding steadiness where you need it most.

• Under-mattress reinforcement helps preserve a firmer feel and encourages even support across the surface without adding bulk.
• Low-profile design maintains a clean, modern look without the height of a traditional box spring.

Size options and practical dimensions

Choose from sizes that align with common frame dimensions: 30 x 60 for double beds, 48 x 60 for queen beds, and 64 x 57 for larger queen frames. The board itself measures 60 inches long by 48 inches wide, providing a centered, balanced base.

• Overall size: 60 inches L x 48 inches W
• Folded size: 48 x 15 inches
• Flat thickness: about 1/4 inch; folded thickness: about 4/5 inch; weight: approximately 11 pounds

Versatility you can rely on

The mattress support is foldable and lightweight, making storage and travel simpler than a bulkier foundation. It suits kid’s beds, bunk beds, sleeper sofas, pull-out beds, sofa beds, or beds with supportive slats, offering a flexible base where you need it most.

Important note: The board is designed to lie in the middle of the mattress, leaving several inches on each side. It is not intended to cover the entire footprint of the mattress.
