Argos, Next or other brand of mid sleeper?

[ActualAl]

Looking to buy a mid sleeper for my 2.5DD. Have researched lots of brands including Thuka,Flexa,and stompa but unfortunately they are a lit,e out of my price range. We moved house 4 weeks ago and DC2 is due in 4 weeks so money is a bit tight. We were hoping to spend £300 or less on frame, mattress and possibly a tent too for underneath.
The 2 beds I quite like are

www.argos.co.uk/static/Product/partNumber/7381461.htm
Does anyone have either of these or have an opinion on their suitability?
Thanks

Cant offer much advice but am also looking a mid sleepers and cabin beds.

I like the Stompa ones best but also cannot afford £800 odd. I have been looking at Stompa secondhand and thinking of getting a new mattress.
