King mattress questions, answered.

How big is a King mattress?
Typically 76 × 80 inches, which is 16 inches wider than a typical Queen. Check the exact mattress and frame dimensions before ordering. Compare mattress sizes.
King or California King, which fits?
A typical standard King is 76 × 80 inches; California King is 72 × 84. Choose between extra width and extra length, and measure the entire frame and surrounding furniture. Explore California King mattresses.
Is Split King the same as King?
A typical Split King uses two 38 × 80-inch Twin XL mattresses to make a 76 × 80-inch sleeping area. Standard King is generally one mattress. Check the exact included pieces, bases, bedding and full-set price before buying. Compare Split King options.
Will it fit through my doorway?
Measure doorways, stairs, landings and tight turns as well as the bedroom. Check the mattress and foundation dimensions and follow manufacturer handling instructions; do not assume every mattress can be folded. Review delivery and setup and ask about access requirements for your order.
How does the comfort exchange work?
Eligible mattresses qualify for one same-size comfort exchange after at least 30 nights and within 120 nights of delivery. There is no exchange fee. Bring the mattress back and pick up the replacement yourself at no charge, or choose pickup and redelivery by our team for $100 total. Pay any increase for a higher-priced replacement; the difference is not refunded for a lower-priced one. This is an exchange, not a money-back trial. Condition requirements and exclusions apply; read the comfort-exchange terms.
Will a King mattress work on my base?
Check the exact mattress and base manufacturer’s support requirements, size and adjustable compatibility. A King label does not prove compatibility. Explore adjustable beds and bases.
Can I try these models in person?
Call your preferred showroom to confirm the exact models and sizes available to try. Online inventory and pickup do not prove showroom display. Find an LA Mattress showroom.
What should my King mattress budget include?
Compare the same King configuration, then include any base or frame, bedding, tax, recycling fee and applicable delivery/removal charges. Check delivery options for your address.
