Our verdict

A low-profile 4 inch foundation for a king mattress, built to sit on an existing frame or platform rather than serve as a stand-alone base.

Overview

A bed frame or platform still has to do the structural work; Zinus's Victor Quick Lock Box Spring just adds a 4 inch low-profile foundation on top, with a steel frame and steel slats under a poly jacquard cover.

This is a foundation, not a bed. It has no legs of its own and depends entirely on a bed frame or platform underneath it, and its main selling point is height: at 4 inches it sits notably lower than a traditional 9 inch box spring, useful under a mattress that would otherwise sit too high.

  • 4 inch low-profile height
  • Steel frame and steel slats
  • 700 lb weight rating (king size)
  • 5 year limited warranty

Who it's for

Fits someone replacing an old, tall box spring under an existing bed frame or platform who wants a lower 4 inch profile instead. It is not a stand-alone bed base, since a frame or platform is still required underneath it.

Pros and cons

Pros
  • Low 4 inch profile under a tall mattress
  • Rated to 700 pounds for king size
  • Quick lock assembly with minimal tools
  • 5 year limited warranty included
Cons
  • Requires a separate bed frame or platform

Performance notes

A steel interior frame with steel slats and a poly jacquard cover supports the mattress at a 4 inch height, low enough to sit under a taller mattress without adding much overall bed height. Zinus rates the twin size to 350 pounds and every other size, including this king, to 700 pounds, and the quick lock hardware is meant to go together without extensive tools.
