Hi All
Yes, I bought a true level for my Haven XL and the first night I slept on it in the bunk was absolutely wonderful, I slept like on a cloud, but then when I had to sleep the second night, yes, I managed to lie on it for approx. 8-10 min. and there was a puff and all the air disappeared, and to my great surprise there was a 10-12 cm long tear in my mattress.
I wrote to Haven and they have now sent me a new one which I look forward to using, however I feel that true level does not fit as wel...
