Help me find a SIM!

[ImWearingPantaloons]

I currently have a 10cm Outwell Dreamcatcher which to be honest is a pain.

It inflates ok however when I sleep on it’s practically flat and compressed on the areas my backside / hips are on to the point that I wake in discomfort (I use it on top of a camp bed as well).

It is also massive when deflated and rolled.

So I’m looking for something that remains quite firm when slept on (doesn’t need to be 10cm) and packs down quite small.

Any suggestIons?

Have you tried blowing extra air into it before shutting the valve?

Has it got a faulty valve? We had one which deflated like that and there was a tiny leak at the valve....discovered when we put it in water.

Yes I’ve tried blowing into the valves (there are two), whatever I blow in seems to blow straight back out at me.

I am looking to replace it as we’re away camping soon, and need something that takes up a little less space in the car

in exactly the same position, with the same SIM (dream catcher 10cm, Outwell) which is deflating on me overnight so watching with interest for any recommendations!

I have the 12.5cm hi-gear one, perfectly comfortable with a bit of air blown in (and im heavier than most!) Rolls down to yoga mat type size.

Jumping on as I need a new one, my hips can't take hard ground in my old age.
Mine is a Thermarest but it's quite old and I suspect not that thick but the biggest problem last time I camped was that I kept slipping off - slippery sleeping bag and mat and a slight slope were a very bad combo!

Ive discovered that a double fitted bed sheet folds around my single 12.5cm mat twice perfectly. The elastic corners hold it in place and it adds extra warmth (we have the jersey type sheets for this)

I’m in the same boat - the Outwell dream catcher’s valves have never worked brilliantly, it always re inflated when stores so it’s huge, and deflated slowly through the night. It was beautifully comfortable when it worked though.
Now it deflates quickly over night I need to replace it and want something with better valves.
Mine is a few years old and from what I’ve seen online, Outwell have changed the valves on the newer models. So what should I get next ? Thermorest is too expensive - another Outwell ? Vango? Berghaus?
