We use single mattress and our tents are placed over the top of the mattress and the breakfast trays at the foot of the bed. Therefore the amount required is as follow

 

The space of each standard teepee is 170cm H x 102 cm W x 160 cm D.

 

Tray is an additional 36 cm depth.

 

We can be clever when it comes to styling to maximise the amount of space available for example placing the tray on the mattress.
