Overview
Internal Fiber-Tech beams run across the Intex Dura-Beam bed, holding its shape so sleepers do not sag into the middle. A built in electric pump fills and empties it, and raised edges add a firmer border.
Bed height and quick inflation make it feel close to a real guest bed. New beds stretch at first, so plan a top up on the first few nights.
Who it's for
Suited to guest rooms and car camping with power. Backcountry campers need a battery or manual pump bed.
Pros and cons
- Tall, bed-like height
- Built in electric pump
- High weight capacity
- Puncture resistant top
- Needs mains power
- Stretches during first nights
- Length and width not listed
Performance notes
Support comes from horizontal beams that tie top and bottom together so the surface stays flat under weight. The built in pump inflates quickly and also deflates for packing. Early air loss is vinyl stretching, which settles after a few nights.
