Deep Pocket Guidance
Pocket depth is how deep the fitted sheet's elastic pocket is – it determines the maximum mattress thickness the sheet can handle. Most Alaskan King mattresses are 10–14 inches thick.
Match your mattress to the right pocket depth:
- 10-inch mattress→ 13-inch pocket minimum
- 12-inch mattress→ 15-inch pocket minimum
- 14-inch mattress→ 17-inch pocket minimum
- 14+ inches (with topper)→ 18–20-inch pocket
Rule of thumb: add 3 inches to your mattress thickness. If you use a mattress topper, add the topper thickness too. A 12-inch mattress with a 3-inch topper needs at least an 18-inch pocket.
Most Alaskan King sheets from OCOCHI and Alaskan King Bed Co. are designed for mattresses up to 14–16 inches thick. If your mattress is thicker or you use a topper, check the pocket depth spec before ordering.
What Sizes Actually Exist
Here's a breakdown of what bedding pieces you can actually buy in Alaskan King (108" × 108") size:
Fitted sheets
Widely available from OCOCHI, Alaskan King Bed Co., Mattress Insider, and Big Mattress Co. This is the piece you absolutely need in the correct size.
Flat sheets
Available in sets from most sellers. An Alaskan King flat sheet is typically 120" × 120" or larger for proper drape. Sold individually by some sellers.
Pillowcases
Included with sheet sets. Standard and King-size pillowcases work (pillow size isn't affected by mattress size).
Duvet covers
Available from OCOCHI and Alaskan King Bed Co. Less variety than sheets.
Mattress protectors
Available from OCOCHI and Alaskan King Bed Co. Highly recommended for protecting a $2,500+ mattress.
Bed skirts
Very limited. Most Alaskan King owners use platform frames that sit low and don't need skirts.
Weighted blankets
Not currently available in 108" × 108" from major sellers.
Budget Path: Getting Started Without Overspending
After spending $2,500–$7,000 on a mattress and another $1,000–$3,000 on a frame, bedding costs can feel like a surprise. Here's how to get started affordably:
Cheapest workable setup
$160–$240 for two setsBuy two microfiber sheet sets from OCOCHI or Big Mattress Co. at $80–$120 each. Microfiber is perfectly comfortable and durable – it just doesn't have the luxury feel of cotton or bamboo. Having two sets means you always have a clean set while the other is in the wash.
Mid-range upgrade
$150–$300 for one setOnce you're settled, add one cotton sateen or bamboo set from Mattress Insider or OCOCHI. Use this as your primary set and keep a microfiber set as backup.
Full setup
$500–$900Two cotton or bamboo sheet sets ($300–$600) plus a comforter or duvet ($200–$500). This is the long-term target, but there's no reason to buy everything at once.
Don't buy everything at once. Start with two fitted sheet sets and a comforter. You can add flat sheets, duvet covers, and decorative pieces over time.
Frequently Asked Questions
What size sheets fit an Alaskan King bed?
Alaskan King sheets are 108" x 108" for the fitted sheet, with flat sheets typically 120" x 120" for proper drape. Standard King (76" x 80"), California King (72" x 84"), and other sizes will not fit - you'll be over 2 feet short in each direction.
Where can I buy Alaskan King bed sheets?
Five verified sellers offer Alaskan King sheets: OCOCHI, Alaskan King Bed Company, Big Mattress Co., Mattress Insider, and Custom Mattress Factory. Prices range from $80 for microfiber to $400 for premium cotton sateen. See our seller table above.
How much do Alaskan King sheets cost?
Alaskan King sheet sets cost $80-$400 depending on material. Microfiber sets run $80-$120. Cotton sateen and bamboo sets cost $150-$300. Premium organic cotton runs $250-$400. Budget tip: start with two microfiber sets ($160-$240 total) while you save for nicer sheets.
Do regular King sheets fit an Alaskan King bed?
No. A standard King fitted sheet (76" x 80") is 32 inches too narrow and 28 inches too short for an Alaskan King (108" x 108"). The sheet won't stay on the mattress. You must buy sheets specifically made for Alaskan King dimensions.
What is a deep pocket fitted sheet and do I need one for an Alaskan King?
Deep pocket refers to how deep the elastic pocket is - it determines the maximum mattress thickness the sheet can handle. Most Alaskan King mattresses are 10-14 inches thick, so you need at least a 15-inch pocket. If you use a mattress topper, add the topper thickness and get an 18-20 inch pocket.
Can I get Alaskan King sheets on Amazon?
Very limited options. Most Alaskan King sheets are sold directly by specialty oversized bed manufacturers. OCOCHI and some third-party sellers occasionally list on Amazon, but selection and availability varies. Buying direct from OCOCHI, Big Mattress Co., or Alaskan King Bed Co. gives you more options and better support.
Are Alaskan King fitted sheets one piece or split?
It depends on the manufacturer. Some sellers like Mattress Insider ship fitted sheets in sections that zip together, matching how their modular mattresses are built. Others like OCOCHI and Alaskan King Bed Company sell single-piece fitted sheets. Check the product description before ordering.
What's the best material for Alaskan King sheets?
Cotton sateen (soft, slight sheen) and bamboo (moisture-wicking, cool) are popular premium choices. Microfiber is affordable and durable but less breathable. For hot sleepers, bamboo or percale cotton work best. Start with microfiber to save money, then upgrade to cotton or bamboo when budget allows.
