100" x 100" Custom Mattress & Beds by Vispring

The 100" x 100" in Practice

The commission at the ceiling of what is possible: buyers for whom this is the defining piece of the house.

There is a version of this bed available from manufacturers who will make anything to any size. What they cannot do is hand-nest a calico pocket spring honeycomb or side-stitch a border by hand at 100" x 100", and those two operations are the entire difference between a bed that holds its shape for decades and one that does not.

Size, Surface and Comparison

At 100" x 100" this bed presents 69.4 square feet of sleeping surface. Set against the 42.2 square feet of a standard 76" × 80" King, that is 64 per cent more area, 24 inches wider and 20 inches longer.

The nearest production size is the King at 76" x 80". This specification exceeds it, and the gap is precisely why the bed has to be commissioned. There is no manufactured mattress that closes it, at any price.

Will It Fit? Room Dimensions and Clearance

Room dimensions govern this choice. A 100" x 100" needs 13'4" x 11'4" at minimum, 151 square feet or so, which accounts for 30-inch walkways on three sides and the depth the headboard takes from the wall.

The comfortable dimension is 14'4" x 12'4". That is not a luxury allowance; it is the point at which two people can pass each other at the foot of the bed without turning sideways.

Delivery, Access & the Staircase Problem

100 inches is beyond what most homes will take by the obvious path. We survey before confirming the order, and where the stairs defeat it, which happens. The answer is usually a window entry or a crane. Both are workable; neither is improvised on the day.

The divan base is built in 3 sections, which resolves the base half of the access question. The mattress is the component that cannot be divided: a Vispring spring unit is a single hand-nested honeycomb with a hand-stitched border. It arrives whole or it does not arrive.

• Every doorway from the street to the bedroom, including the front door, which is more often the constraint than people expect.
• Stairwell diagonals; the critical figure at any change of direction, and the usual reason a delivery fails.
• Ceiling and soffit heights; 100 inches of rigid mattress needs somewhere to go when tilted.
• Lift car depth: the door width and the internal depth are different numbers; both matter.
• Contingency access. Window or balcony entry, which we can arrange where the interior route will not serve.

The Linen Question

No mass-market bedding is cut to 100" x 100". 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.

One point specific to this width: at 100 inches, a duvet that drapes correctly should measure roughly 132 to 144 inches across, allowing a proper fall on both sides over a mattress of Vispring depth. A cover cut to the mattress width alone sits on the bed, not over it, and the difference is immediately visible.

The Look of a 100" x 100"

This is a construction project as much as a purchase. The base ships in multiple sections, the delivery route must be surveyed in advance, and every piece of bedding is made to order. Expect an extended lead time and plan the room, the access and the linens together as a single brief.

A true square has no long axis, which changes how the bed is read. It centres naturally on any wall, never looks accidentally placed, and is the most forgiving proportion to photograph. It is also the least forgiving of asymmetry. Matched nightstands and centred lighting are effectively compulsory.

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.

Hand-Building to 100" x 100"

A built-to-order size is not a variation on a standard product. It is the standard process applied to your numbers. For a 100" x 100" that means a craftsperson pocketing each spring in calico and tying the honeycomb by hand to a 100 by 100 footprint. Density is fixed, so the count lands near 164 per cent of a King's.

Above the springs sit the natural fillings, teased apart by hand and laid across all 69.4 square feet before being tufted through. Then the border is side-stitched; stitches drawn by hand through the mattress edge to hold the sidewall vertical. On a bed this size that edge work is what keeps the perimeter as usable as the middle.

Collections available at this size

The Original, Classic and Luxe collections can all be specified at 100" x 100", with the natural filling composition and spring count varying by collection. Per-collection availability and specification at this dimension to be confirmed, Vispring dealer schedule
