We use the Coleman Ridgeline 4 and a few similar type tents.
All tents are a viz a viz style with 2 separate sleeping compartments and full standing height in the living area.
Roll mats are included with all tents — air beds an option.
For those who can't view images in their browsers, the tents are two separate sleeping compartments either side of a central living area.
The central area is 205 cm at its highest point, sloping down to 160 cm at the sleeping compartments.
The sleeping compartments are 140 cm wide by 210 cm deep. The central area between them is 160 cm wide (and, unsurprisingly, is also 210 cm deep).
