King Koil Air Mattress California King with Built-In Pump — Coil-Beam Support, Flocked Top

The King Koil California King air mattress is a luxurious, coil-beam inflatable bed with a fast built-in pump that delivers real-bed comfort for two adults.

Designed to combine travel-ready portability with the supportive feel of a traditional mattress, this King Koil CALIFORNIA KING inflatable bed uses patented coil-beam construction and a flocked top to prevent sagging and improve sleeping posture. It inflates quickly with a high-speed 120V/210W AC pump and deflates for compact storage, making it suitable for guest rooms, camping, and temporary sleep setups where comfort matters.

How long does the mattress take to inflate and adjust firmness?

The built-in high-speed pump inflates the King Koil Cal King in about two minutes, so setup is fast and simple. Separate inflate and deflate controls make it easy to fine-tune firmness to your preference or let air out quickly for packing.

• Inflates in ~2 minutes with 120V / 210W AC pump
• Distinct inflate and deflate knobs for quick control
• Adjustable firmness to suit side or back sleepers

What makes the coil-beam design better than a standard airbed?

Patented coil-beam construction creates vertical support that reduces sagging and maintains a firmer, mattress-like surface. That structure helps stabilize the sleeping surface for two adults and supports a healthier sleeping posture compared with flat air chambers.

• Vertical coils mimic traditional mattress support
• Resists sinkage overnight, even with two sleepers
• Flocked top adds traction and a softer, mattress-like feel

Is this air mattress suitable for travel and easy storage?

Yes—while it offers California King dimensions and a raised height, the mattress deflates quickly into a compact package for transport or storage. Its durability and fast pump make it practical for weekend trips, overnight guests, or seasonal use without permanent space commitments.

• Deflates rapidly for compact storage
• Durable materials chosen for repeated inflation cycles
• Large size still folds down to a portable footprint
