78" x 78" Custom Mattress & Beds by Vispring

Which Sleepers Choose a 78" x 78"

Clients furnishing to European standards, and buyers who want a square bed in a proportion with genuine provenance rather than an invented dimension.

People generally arrive here after replacing a mattress and discovering the problem was never the mattress. If the geometry is wrong, quality cannot fix it; a firmer bed of the wrong dimensions is still the wrong dimensions. A 78" x 78" addresses the actual variable.

Size, Surface and Comparison

At 78" x 78" this bed presents 42.3 square feet of sleeping surface. Set against the 42.2 square feet of a standard 76" × 80" King, that is 0 per cent more area, 2 inches wider and 2 inches shorter.

The King at 76" x 80" is the nearest standard equivalent, which tends to be the size people own when they first enquire about this one. The step between them is not a refinement; it is a different bed.

Fitting a 78" x 78" Into a Bedroom

Plan for 11'6" x 9'6" as the minimum. That figure, about 109 square feet. Is the 78" x 78" mattress plus 30 inches of walk-around on both sides and at the foot, plus the six inches a headboard claims from the wall.

We would recommend 12'6" x 10'6" or better. The extra six inches per side is the difference between edging around the bed and moving around it freely, and at this scale that distinction is felt every morning.

Why Access Is Settled Before the Order

78 inches on the longest side keeps this bed within conventional access limits. It is among the easier custom sizes to deliver, and in most homes the crew will have it in position without incident.

Base construction runs to 2 sections, joined once in position. That flexibility does not extend to the mattress. The spring honeycomb is nested as one piece and the border stitched through by hand, so the mattress is delivered intact or not at all.

• The narrowest doorway on the route. Measure the clear opening with the door removed, not the frame.
• Stair width and turns. A 90-degree turn needs diagonal clearance, not merely width. This defeats more oversize deliveries than anything else.
• Ceiling height at the turn. A 78-inch mattress carried on edge needs vertical room to pivot.
• Lift dimensions, in apartment buildings, measure internal depth and door width separately.
• Window access, where the stairs will not take it, a crane or window entry is often the answer. Better known before ordering than after.

The Linen Question

You can buy linens for this size. 78" x 78" appears in the catalogues of oversize bedding suppliers, which means replacement sets, seasonal changes and spares are all a purchase, not a project.

For the duvet, work from 110 to 122 inches across and not the 78-inch mattress measurement. The extra width is what falls over the sides, and on a bed this size that fall is most of the visual effect.

The Look of a 78" x 78"

At 200 centimetres square the bed sits almost exactly between a standard King and a Wyoming King in surface area, while reading as far more considered than either. European duvets in 240 by 260 drape this size correctly.

Square beds behave differently in a room. Without a dominant direction they sit as a deliberate object instead of a piece of furniture pointed at a wall, and they reward strict symmetry: paired lamps, paired tables, art centred over the headboard.

At 78 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 78 inches tends to read as undersized once the bed is dressed.

Hand-Building to 78" x 78"

The distinction between hand-nested and machine-assembled matters most at large sizes. A 78" x 78" spring unit is tied together by hand across its full 42.3 square feet, which keeps tension consistent to the very edge, where oversized machine-built mattresses characteristically fail. Spring count scales with area to about 100 per cent of a King's.

The fillings follow the same logic. British fleece wool, horsetail hair, cotton and, in the upper collections; cashmere and silk are hand-teased in layers across the full 42.3 square feet, then secured by hand-tufting. The border is side-stitched by hand: a row of stitches drawn through the mattress edge that holds the sidewall upright and prevents the roll-off that afflicts machine-finished mattresses at scale.
