Overview
OSASET's box spring is a 9 inch metal foundation sized for a queen mattress, rated to support up to 3000 lbs, usable with a basic bed frame or set directly on the floor.
As a foundation rather than a mattress, fit questions matter more than anything else: this is a queen-size-only metal frame, not a wood-slat box spring, and the listing states it can sit on the floor without any frame at all or pair with a basic frame for extra height. No owner review text came with this listing to confirm the noise-free claim in daily use.
- 9 inch profile
- Queen size only
- Rated to support up to 3000 lbs
- Works with or without a bed frame
Who it's for
Fits someone replacing an old queen box spring or adding height under a queen mattress without buying a full bed frame. Not a fit for any other mattress size, since this listing is queen only.
Pros and cons
- Works on floor or with a frame
- Rated to support up to 3000 lbs
- Removable cover for easy cleaning
- Stated quick assembly with included tools
- Queen size only, no other sizes
Performance notes
The 9 inch metal frame raises the mattress to standard bed height when set on the floor, or adds to whatever height a basic frame already provides. The cover is a removable fabric that comes off for cleaning, and the listing states assembly takes minutes with the included tools.
