Overview
This is a 9 inch profile metal box spring built for queen mattresses, giving a queen mattress the added height and even support that a worn or missing foundation no longer provides.
It is a foundation piece rather than a mattress itself, model YBS904, meant to sit under a queen mattress and keep it from sagging while lifting the overall bed height. A washable fabric cover finishes it off so it does not look like exposed hardware in a made-up bedroom.
- 9 inch profile height
- Metal frame construction
- Washable fabric cover
- Model YBS904, queen size
Who it's for
Fits queen mattress owners who need a real foundation rather than a platform frame, particularly anyone replacing a squeaky or sagging original box spring. Not for platform bed owners who already have slat support and do not need the extra 9 inches of height.
Pros and cons
- Washable cover keeps the foundation looking clean
- Compact packaging makes it easier to move
- Metal build aims to resist sagging and noise
- Fixed 9 inch profile wont suit lower setups
Performance notes
The metal structure is meant to spread a mattress's weight evenly across the frame rather than letting it rest on a few points, which is what keeps sagging and squeaking down over time. Its 9 inch profile is the main dimension to check against an existing bed frame height before buying.
