If you're on a budget, i've had a Highlander one for two years. Just inflate and deflate as you got. Even if you forget to deflate, as it's 3/4 it seems to manage to fold up nicely!

Mountain Equipment Helium 3.8 warmzone. Currently £55 on eBay. Heavy duty valve. Fits perfectly inside of the bedchair outers, really comfy too.

I definitely don't suggest blowing it up. I tend to open the valve upon setting up, giving it a few long breaths and then let it settle itself over half an hour or so before closing the valve.

Another plus is opening the valve and just folding up your bedchair. I store it that way too in between visits to the lake.

These are excellent as recommended on here by the legend that was Gerry. Very comfortable and totally transform a bedchair.

Just remember to shut the valve before sitting on your bed-chair, as you can squeeze the air out again if you forget ( I am very absent minded).

Another good thing is that it is easy to slip out from underneath the bag and you can roll it to squeeze all of the air out and slip it back into pack the bedchair up.

Mountain warehouse helium sim has lived inside my bedchair for 6 years. I open the valve for a minute to let a little air in before use. I don't like it over inflated.
I bought mine second hand on ebay, I fish 2 nights a week and its still going strong.

I have always recommended a 3/4 length sim rather than a full length one as it gives better support on your high pressure areas of shoulder and hips.

As well as my 3/4 thermarest thats on my bedchair I also have a full length thermarest.
If I lay on the full length one all the air gets pushed to the foot endand I can feel my feet lifting up a bit.
My shoulders and hips are then flat on the bedchair, and its even worse if you are a side sleeper.

If you have a full length sim then try folding it in half, but dont over inflate.
When folded over it is 90cm in length and thats now long enough to cover shoulders and hips.
Give it a try 5
