Evening Geoff,
Yes as you say, big business!
There's alot of companies out there at the moment having a stab at the pressure mattress industry....and failing miserably!
I've had lots of mattresses in for repair from various companies and i cannot belive that the build quality passes any uk standards. Many of these companies (this is why i don't call them manafacturers) have pressure systems mass produced & imported from mainly China. Recently i was inspecting a pump from one of these imported systems and found the live wire to be BLUE & the earth wire to be RED!!
I could go all day on these faults..... If i ever have to use one of these systems, i will take the option the lay on a concrete floor, as i would be more likely to recieve pressure relief from their!!
Although Huntleigh/arjo are expensive they are truly the masters of pressure relieving equipment, so my advice to anyone shopping around would be stick with who knows best (but that is of course just my opinion).
Cheers,
