Ordered a new sleep mat today, I was going to get one from Kilos Gear where my chair came from but the one they do is 5cm shorter than I wanted, I was recommended to one on Amazon that goes for only £35 so I thought for that I will take a punt, in the end it had a discount on it so got it for £28. The one I really like is £250 and I will not be surprised if I end up with one of those in the long term but let’s see what this budget option is like.
