SIM?

[dannyboyle]

So what am I doing wrong?
Have had two vango SIMS now, both hopeless and losing air out of the valve during the night to point after a few hours we might as well be on the floor. Before these we had the standard blow up flock air mattress thing. All I want is a decent mattress for camping and weekends at family where we to sleep on the floor?
Camping shop can't help just say that's how they are and some will go (after 3 uses at £80 odd quid?)

So what do I get now that will work (think I have lost confidence in SIMs and those valves!

Are you heavier than average OP? If not I think you should complain directly to the company that makes them!

Nope, both normal range. Am going to complain, but there must be something else out there??

That shouldn't happen!
I have both cheap Aldi SIMS and a Coleman one, and another of unknown make. None have had leaky valves, and have been used many times.

Agree Aldi/Lidl ones good as long as cat doesn't chew them. Last year they were in shops around summer half term time.

Expedit 10cm double SIM. Heaven!

Also have Aldi ones are they have never done this
