2 Inch Low Profile Posture Board Foundation (Boxspring)
2 Inch Low Profile Posture Board Foundation (Boxspring)
- Minimalist Profile: Typically only 1.5 to 2 inches thick, making them ideal for keeping the bed low or for use in bunk beds, daybeds, and platform frames.
- Solid Surface Support: They create a uniform, non-flexing surface. This is critical for foam mattresses like the Restonit Patricia, as it prevents the foam from sagging between the gaps of widely spaced slats.
Restonit Posture Boards (also referred to as Bunkie Boards) are ultra-low-profile boxspring designed to provide a flat, rigid support surface for your mattress without adding significant height. They are the slim alternative to standard 7-inch or 4-inch box springs.
Key Features & Use Cases
- Minimalist Profile: Typically only 1.5 to 2 inches thick, making them ideal for keeping the bed low or for use in bunk beds, daybeds, and platform frames.
- Solid Surface Support: They create a uniform, non-flexing surface. This is critical for foam mattresses like the Restonit Patricia, as it prevents the foam from sagging between the gaps of widely spaced slats.
- Construction: Usually made of a spruce wood frame covered in durable fabric, often with internal slats or a solid MDF panel to ensure a high weight capacity (up to 800 lbs).
- Warranty Compliance: Using a posture board satisfies the foundation requirements for most Canadian mattress warranties while maintaining a sleek, modern look.
Note: If you are putting a memory foam mattress on an old box spring to save money, placing a posture board on top is a common “hack” to convert it into a solid, foam-safe foundation.
