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?
You need sheets specifically made for Alaskan King dimensions (108" x 108"). Standard King, California King, and other sizes will not fit.
Where can I buy Alaskan King sheets?
Most oversized mattress manufacturers sell matching sheets. Big Mattress Co, OCOCHI, Alaskan King Bed Company, and Mattress Insider all offer Alaskan King sheet sets.
How much do Alaskan King sheets cost?
Expect to pay $150–$400 for a quality Alaskan King sheet set. Prices vary by thread count and material. Cotton sateen and bamboo options tend to be at the higher end, while microfiber blends are more affordable.
Can I use King or California King sheets on an Alaskan King bed?
No. A standard King sheet fits a 76" x 80" mattress and a California King fits 72" x 84". Neither will cover a 108" x 108" Alaskan King–you'll be short by over 2 feet in each direction. You need sheets specifically made for Alaskan King dimensions.
Are Alaskan King fitted sheets one piece or split?
It depends on the manufacturer. Some sellers like Mattress Insider ship bedding in sections that zip together, matching how their mattresses are constructed. Others like OCOCHI and Alaskan King Bed Company sell single-piece fitted sheets. Check the product description before ordering.
