Who the 100" x 84" Is Built For
Buyers who have decided the bed is the room, and want maximum width without the perfect-square formality of the 100 by 100.
The made-to-measure route is not exotic and it is not a favour. Vispring's factory has no production line to interrupt: every bed is built by hand at a bench, so a 100" x 84" is simply a different set of measurements handed to the same craftsperson who would otherwise be building a Queen.
Putting 58.3 Square Feet in Perspective
At 100" x 84" this bed presents 58.3 square feet of sleeping surface. Set against the 42.2 square feet of a standard 76" × 80" King, that is 38 per cent more area, 24 inches wider and 4 inches longer.
| Size | Dimensions | Surface | vs. King |
|---|---|---|---|
| Twin | 38" × 75" | 19.8 sq ft | -53% |
| Twin XL | 38" × 80" | 21.1 sq ft | -50% |
| Full | 54" × 75" | 28.1 sq ft | -33% |
| Queen | 60" × 80" | 33.3 sq ft | -21% |
| California King | 72" × 84" | 42 sq ft | -1% |
| King | 76" × 80" | 42.2 sq ft | 0% |
| Maximum Wide Long (this size) | 100" × 84" | 58.3 sq ft | +38% |
Among standard formats the King at 76" x 80" comes nearest. Most clients who specify 100" x 84" have already ruled it out, usually on the basis of a single dimension that could not be fixed by buying a better version of the same shape.
Planning the Room
Before the specification is finalised, measure the room. A 100" x 84" occupies its space uncompromisingly, and the minimum viable footprint including circulation is 13'4" x 10', or roughly 133 square feet.
14'4" x 11' is the figure we would put on a plan. It allows 36 inches of circulation, which is the difference between a bedroom containing a large bed and a bedroom built around one.
Measure before you specify
Before anything is confirmed, mark 100 by 84 on the floor and walk the room for several days. Drawings and figures do not convey scale; a taped rectangle does, and it costs nothing to be wrong at this stage.
Access, Doorways and Delivery Planning
Delivery is a planned operation at this size. The 100-inch mattress is a single rigid piece that cannot be reduced, and the route from the street to the bedroom has to be established in advance. We survey it, and we tell you honestly if it will not go.
With the divan built in 3 sections, the base will follow almost any route into the house. Plan around the mattress instead. It is one rigid piece, 100 inches at its longest, and it does not compromise.
- Front door and hallway. The entry point defeats more deliveries than the staircase does.
- Turning circles. Measure the diagonal at every corner; a 100-inch panel needs the space to swing.
- Vertical clearance. Low ceilings and pendant lights restrict how far the mattress can be tilted.
- Bedroom door approach. A door at the end of a narrow corridor is a harder problem than a wide one.
- Plan B; crane or window access, which is routine at this scale and worth pricing early.
The Linen Question
No mass-market bedding is cut to 100" x 84". Fitted sheets, flat sheets and protectors are made to order, and a duvet sized for the nearest standard bed will sit short once mattress depth is accounted for. We supply a written linen specification with every bespoke order so any competent linen house can cut to your exact dimensions.
Get the duvet width right and the bed dresses itself: 132 to 144 inches over a 100-inch mattress. Get it wrong and no amount of styling compensates, because the cover will simply stop at the mattress edge.
The Look of a 100" x 84"
Everything at this specification is made-to-measure: base sections, headboard, bedding, and the delivery plan. Treat the order as a commission with a lead time instead of a purchase with a delivery date.
This bed is wider than it is long. An inversion of conventional proportion that reads as distinctly generous. It needs a wall broad enough to carry it, and rewards a headboard conceived as architecture, not furniture.
A note on the 100" x 84"
Maximum width with real length, and the largest bed here that is not a square. Clients choosing between this and the 100 by 100 usually settle it on room shape: a rectangular room takes this comfortably, while the square demands a room that is itself close to square.
At 100 inches wide this bed exceeds every standard headboard on the market, so the headboard becomes a bespoke item commissioned alongside the mattress. Vispring upholsters headboards in the same fabric ranges as the divan, and at this width we would generally advise a piece that runs wider than the mattress instead of flush to it, a headboard cut exactly to 100 inches tends to read as undersized once the bed is dressed.
How Vispring Builds This Size
Hand-nesting is the operation that defines the bed. For a 100" x 84", springs are pocketed in calico and tied into a honeycomb sized to 100 by 84 from the outset. Since Vispring holds spring density constant across sizes, the count rises with the footprint, here to roughly 138 per cent of a standard King's.

After the spring unit come the fillings: British fleece wool, horsetail hair, cotton, and in the upper collections cashmere and silk, teased by hand and distributed across the whole 58.3 square feet before hand-tufting locks them in. The side-stitched border is the last hand operation and the one that determines how the bed ages.

No. The tension change happens within a single continuous spring honeycomb, not between two mattresses pushed together, so the sleeping surface stays unbroken across all 100 inches.
Not off the shelf. Every order includes a written linen specification so a linen house can cut fitted sheets, flat sheets and protectors to your exact dimensions. Most clients commission two or three sets at the outset.
They are nested by hand into a honeycomb built to 100 by 84 inches, not cut down from a larger unit. That is why support holds right to the edge. Exact counts by collection to be confirmed, Vispring specification sheet
Nothing is held in stock at this dimension: the bed is begun when you order it and built by hand in Plymouth. Current lead time to be confirmed, Vispring bespoke schedule We give you a firm date once the specification is agreed.
No; the divan for this size is built in 3 sections and joined in position, which is what makes delivery practical. The mattress cannot be divided the same way; it is a single hand-nested unit.
