I've been in Aldi today and they're Intex which I found to be great beds and very reliable, £34.99 for the double raised is also a very good price.
I've got the same bed bought from Amazon 2 years ago at over £40, done a full season on a seasonal pitch and now used as spare bed at home as I have now got a static.
I bought one 4 years ago (also for a seasonal pitch)and replaced it with another at the end of last year. Very comfortable and, if it lasts as long as the last one, I will be more than happy.
