Who benefits from each support system?
Choose The Frame for a headboard
The $45 upgrade is practical when the bed design needs attachment points
The Frame keeps the same basic platform job as Mínimo, then adds openings for many conventional headboards and raises the mattress two inches. The extra half-inch of clear storage height is modest; the headboard connection is the stronger reason to spend more.
Choose Gold or Black by the room: their construction and current starting price match. The finish is the literal difference.
Keep the $45 with Mínimo
Mínimo is the stronger value when you want a clean platform without a headboard
Mínimo still provides closely spaced birch-laminated slats, open storage, steel construction, and tool-free setup. Giving up headboard attachment points and two inches of total height does not reduce the core support job. Gunmetal and Snow White share the same current price and functional design.
Add height to an existing frame
The Base solves a moving and elevation problem
The bi-fold steel core arrives compact and unfolds without tools, making it easier to carry through stairs and tight hallways than a rigid box spring. It can raise the mattress and recreate a traditional foundation setup. It is unnecessary when a suitable platform already puts the mattress at the height you want.
Our recommendation
Choose Mínimo for the best platform value when no headboard is planned. Spend $45 more on The Frame when headboard openings or the taller visual profile matter. Buy The Base only when you already have a suitable frame and specifically want extra mattress height or a folding foundation that is easier to move.

What does The Frame add over Mínimo?
The Frame adds built-in openings for many conventional headboards and raises total height from 12 to 14 inches, increasing listed storage clearance from 10 to 10.5 inches. The current starting-price difference is $45. Both use steel frames and closely spaced birch-laminated slats, and neither requires a box spring.
Do I need The Base with a KEETSA mattress?
No. KEETSA says its mattresses can sit directly on a suitable flat platform or one of its steel frames. The Base is an optional folding foundation for shoppers who already have a compatible frame and want added height or a more traditional box-spring setup.
Can Mínimo attach to a headboard?
KEETSA says Mínimo does not include headboard attachment points. Choose The Frame when attaching a conventional headboard is part of the plan.
What are KEETSA's bed-frame return and warranty terms?
KEETSA currently lists a 30-day return policy with no break-in period for bed frames, free shipping to the contiguous 48 states, and a five-year warranty for material and workmanship. Confirm the selected size, return condition, and any costs before ordering.
