Just used this tent for the first time at Sonisphere (Knebworth, UK). The bedroom area is huge, fitted a double airbed, as well as our bags, & plenty of space all around the edges. I am 6' 2" & it was fine for me. I couldn't stand up tall in the bedroom area, but I only had to hang my head - amazing compared to most tents.
The bedroom area can be separated into 2 separate bedrooms with a spare piece of material that can be hooked up quite easily (although we didn't bother as we preferred the single large area). There is no mention of this in the instructions, so this is what the spare bit is for!
The living area is even taller - I could stand up straight. Masses of room for storage, sitting about, etc.
The zips & seams are all strong - no sign of problems. The tent stayed completely dry inside - and it was raining very hard for times. Coped fine with quite strong winds too.
Easy to put up as the inner tent is attached already, so literally just thread the poles through the loops, & then peg the guy ropes etc. Don't make the same mistake we initially did - do not pull the poles as far apart as possible, as this then makes zipping up the doors difficult - there should be a natural curve inward for the poles, the tent remains taut, but zips fine.
Fabulous tent - fabulous value for money - no hesitation - get this tent !!
