Mattress Box Foundation for Reliable, Quiet Mattress Support
The Mercer mattress box foundation provides a dependable support layer beneath your mattress while giving you the flexibility to choose the height that works best for your bedroom. Available in 5-inch low profile and 9-inch standard profile configurations, this foundation makes it easy to achieve the desired mattress height without changing the overall character of your bed.
Handcrafted slats create a stable base designed to cradle and support the mattress, while Kara-Guard padding helps reduce unwanted noise between the foundation and mattress. The open construction also promotes airflow around the support system, making this a practical foundation choice for everyday bedroom use.
Choose Between Low Profile and Standard Height
The two available height options let you customize the foundation according to your preferred mattress elevation and bedroom setup.
- 5-Inch Low Profile: Creates a sleek, streamlined appearance and keeps the mattress closer to the bed frame.
- 9-Inch Standard Profile: Raises the mattress to a more traditional height for easier access and a more substantial foundation profile.
- Multiple Sizes: Available in Twin, Twin XL, Full, Queen, Eastern King, and California King.
- Consistent Construction: Both height options feature the same handcrafted support approach and noise-reducing Kara-Guard padding.
Handcrafted Slat Support
The foundation is built around a carefully arranged slat system that provides dependable support beneath the mattress. Rather than simply serving as a platform, the slats are designed to help distribute the mattress load across the foundation for a stable sleeping surface.
The thoughtful construction makes the Mercer foundation suitable for shoppers looking for a reliable foundation that complements a wide range of bedroom styles, from classic transitional interiors to more streamlined contemporary spaces.
Quieter, More Comfortable Bedroom Setup
Kara-Guard padding replaces ordinary cardboard materials to help minimize unwanted sounds created between the foundation and mattress. This detail is especially useful for sleepers who value a quieter bedroom environment.
The foundation’s open structure also allows air to circulate around the support system, contributing to a more breathable mattress setup.
Key benefits include:
- Kara-Guard padding helps reduce foundation noise
- Open construction encourages airflow
- Handcrafted slats provide stable mattress support
- Grey fabric upholstery offers a neutral appearance
- Transitional styling works with a variety of bed frames
- Made in the USA
