Imperius Foldable Box Spring & Bunkie Board – Queen 64x58 Bed Support

Smart, low-profile mattress support for a variety of beds

The Imperius Foldable Box Spring offers a practical alternative to a traditional box spring. Designed to add mid-mattress support, it helps minimize mattress sag and deformation while keeping the bed height modest. Its lightweight, foldable build makes storage simple and travel lighter, so you can refresh a wide range of sleeping setups without adding bulk.

Two quick overviews of what you gain:

• Low-profile design that preserves bed height and maintains a clean silhouette.
• Mid-mattress support that stabilizes the surface for a more even feel.
• Foldable and portable, easing packing, storage, and transport.
• Lightweight construction suitable for temporary or seasonal use.

Designed to fit a broad set of frames, this under-m mattress solution is ideal for kid’s beds, bunk beds, sleeper sofas, pull-out beds, and beds with supportive slats. The board measures 58 inches long by 64 inches wide and is ultra-slim at 0.18 inches thick, with a total weight around 40 pounds. This combination delivers stable support without adding the bulk of a traditional box spring.

• Queen 64" x 58" dimensions provide broad coverage across standard sleeping surfaces.
• Lightweight and foldable for easy storage when not in use.
• Resilient mid-mattress support helps maintain the mattress’s shape over time.
• Compatible with beds that use slats, frames, or other under-bed supports.

Important note: The board is not intended to cover the entire mattress. It is designed to lie in the middle with several inches on each side, providing focused support where you need it most. When in use, you’ll enjoy a firmer, more stable surface without the height or bulk of a traditional foundation. The Imperius solution combines practical engineering with everyday comfort, offering a versatile way to refresh existing bedding setups.

In short, this under-mattress support brings a practical blend of sturdiness, portability, and adaptability to a range of sleeping arrangements. Consider it as a flexible option to improve surface stability while keeping your bed setup neat and easy to manage.
