I bought this tent as an upgrade to my Gelert Twister 3, after safely testing my toddler on a few camping trips and finding she loved it as much as I did! This is a great family-size tent and is genuinely easy to put up and take down. Although the famous video on the Decathlon site shows 2 people putting it up and down, I have done it by myself with no problem on a couple of occasions now. It can be slightly trickier doing it in the wind, but it was still manageable.
On our week-long trip, we had AWFUL weather - very strong winds and torrential downpours with thunder and lightning... and the Base Seconds 4.2 stood up to all of it without a single hitch and stayed bone dry inside. The bucket-shaped groundsheet meant no water at all can run into the tent, even when pitched on an incline. It really, really was put through its paces and I'm delighted with it - cannot fault it. Also, an added bonus for us was that it was just myself and my daughter in this tent, so I used the second bedroom as our storage/junk room to put all our clothes etc., and we slept in the other bedroom. The bedrooms are, I should say, only big enough to put in a double inflatable mattress - there's not really any 'extra' room left over (maybe a few inches at the head or foot end, but not at the sides of the mattress), so you'd definitely need to consider where you'd store clothing etc. if you're using both the bedrooms to sleep in. The living area is a very decent size - the centre part is the genuine 'stand up in it' bit, and you could easily fit four 'normal' camping chairs in there, or one of those folding picnic table jobbies, to give you an idea of size. There are two semicircular bug-netted windows in the main door and also the side opposite, so you can still see the skies outside and let some fresh air in, without letting the bugs in too.
You can also buy other Quechua pop-up tents to fit onto this to add an extra bedroom or a kitchen tent if you wanted - the Base Seconds Full is, I believe, the best one to choose for this, so very versatile indeed if you wanted to add space. For our uses though and as it's just the two of us, this is a perfect, easy to pitch, durable, very very weatherproof, very spacious family tent and would thoroughly recommend it to anyone looking for similar! Also, from the inner dimensions of the living area in this, the Coleman green chequered tent carpet 230 x 230 size, currently discounted to half price on Amazon, would fit if you wanted to add that too! I've just ordered one!
