Alaskan King Bed Sheets

Alaskan king bed sheets cut for the 108 × 108 in. square mattress that mainstream bedding brands stop short of. Our Alaskan king bed sheets are 100% extra-long-staple cotton woven as sateen at 500 thread count, with an 18 in. deep pocket, full-perimeter elastic and an oversized 136 × 124 in. flat sheet built to the size rather than adapted to it — made to order in 21 days.

What an Alaskan king actually is

An Alaskan king is 108 inches by 108 — a square bed, nine feet on each side, thirty-two inches wider than a standard king. Buying one is the easy part. Dressing it is where owners discover that the entire mainstream bedding market stops at 76 inches wide, and that the two king sets they bought “to layer” do not solve anything.

Why Alaskan king bed sheets have to be cut for the size

Our Alaskan king bed sheets are cut for the size rather than adapted to it. The fitted sheet is made to the full 108 × 108 footprint with an 18-inch pocket and elastic around the entire perimeter — essential on a mattress this wide, where a corner-gathered sheet has no chance of staying seated overnight. The flat sheet is cut oversized so there is real drop on all four sides, measuring 136 × 124 in.; on a square bed a flat sheet sized by proportion rather than by rule looks wrong immediately.

Laundry considerations at this size

One consideration specific to Alaskan king bed sheets: a single sheet at these dimensions is a large, heavy piece of laundry, so weight and drying time deserve more thought than they would on a queen. A domestic washing machine may not comfortably take it. The fitted sheet finishes at 2.4 kg dry — wash in a machine of 9 kg capacity or larger. In a smaller machine, launder the fitted and flat sheets separately.

Made to order — every set

Cut to order in 21 days; every Alaskan king set is made against the order rather than held in stock. That is why our lead time is transparent — mattresses at this size are individual investments, and the sheets are made to match a specific bed rather than shipped from a warehouse of standard sizes.

Alaskan king bed sheets — the sizes it isn’t

Related oversized sizes get confused constantly and are not interchangeable:

• Wyoming king: 84 × 84 in. (also square, smaller)
• Texas king: 80 × 98 in. (longer, not square)
• Alaskan king: 108 × 108 in. (this listing)

Measure the mattress itself before ordering — frame dimensions are not mattress dimensions at this end of the market, and the wrong size is unusable.

How to care for your Alaskan king bed sheets

• Wash in a 9 kg+ machine — smaller machines will not spin properly at 2.4 kg dry weight
• Warm wash on a normal cycle
• Tumble dry low with extra time — large sheets take significantly longer than standard sizes
• Line dry outdoors when weather permits — much faster than tumble drying
• Skip fabric softener — softener dulls the sateen luster
• Iron on the reverse from damp if a pressed finish is desired
