Works with your bed frame
Box Spring
A box spring is a sturdy, supportive foundation between the mattress and the bed frame. It consists of a wooden or metal frame filled with springs and covered in fabric, providing extra height and enhancing mattress durability.
Your Firm Mattress works with this foundation.
Divan Bases
Divan bases are upholstered bed foundations with built-in storage options, such as drawers or ottoman-style lift-up bases. They are designed to provide both support for the mattress and practical storage solutions, often featuring a sleek and minimalist appearance.
Your Firm Mattress works with this foundation.
Traditional Frames
Traditional bed frames are classic wood or metal structures that support a mattress and box spring. They usually include a headboard, footboard, and side rails, offering a timeless aesthetic that complements various bedroom decors.
Your Firm Mattress works with this foundation.
Platform Beds
Platform beds are low-profile frames with a solid or slatted surface to support the mattress without needing a box spring. They offer a modern, streamlined look and often include built-in storage options, making them a practical choice for contemporary bedroom designs.
