Alaskan King Bed Price: Full Cost Breakdown
An Alaskan King bed is a significant investment. At 108" × 108" (9 feet square), everything about it is custom – the mattress, the frame, the sheets. That means higher prices than standard beds across the board. Here's exactly what to expect.

Why Prices Vary So Much
Materials
All-foam mattresses are typically cheapest ($2,000–$3,500). Hybrids with coils run $3,000–$5,000. Latex or organic options push $4,000–$7,000+.
Construction
Modular mattresses (Engineered Sleep, Big Mattress Co.) cost more upfront but let you replace worn sections instead of the whole bed. Single-piece mattresses are simpler but non-repairable.
Customization
Dual-firmness (different feel on each side), adjustable layers, and custom dimensions add cost. A basic single-firmness mattress is the most affordable option.
Brand Positioning
Direct-to-consumer brands like Big Mattress Co. and Nolah tend to price lower than custom workshop operations like Sleep Boutique or Alaskan King Bed Co.
Alaskan King Bed Frame Prices
A standard King frame won't work – you need a frame built specifically for a 108" × 108" mattress. Options range from simple platform frames to upholstered designs.
- Platform frames (wood)$1,000–$2,000
- Metal platform frames$800–$1,500
- Upholstered frames$1,500–$3,500
- Custom/designer frames$3,000–$5,000+
- Foundation/box spring alternative$500–$1,500
Important: Center support is critical at this size. Look for frames with multiple center support legs or a full-platform design. Slats alone may not be enough for a 9-foot span.

- Fitted sheet sets (fitted + flat + pillowcases)$150–$400
- Comforters/duvets$200–$500
- Mattress protectors$80–$200
- Duvet covers$100–$300
Alaskan King bedding is harder to find than the mattress itself. Only a few sellers carry sheets in this size – OCOCHI, Alaskan King Bed Co., Big Mattress Co., and Mattress Insider. Expect to buy bedding from your mattress seller or a specialty oversized bedding shop.
