we were given the elc one second hand, and i would not buy it, whatever the price - never mind £50! that said we did use it, but it had to be leant up against the sofa or something to stop it from toppling over when hayden leaned against it! it was very flimst - just an inflatable ring, held onto a mat with velcro, so didn't give any support really. sounds like there are some better options out there.
