good luck with the water bed, I slept on one for a couple of nights in the US and it was heaven but I was warned that if used all the time they could cause back ache, in the US I believe you cant install one if you live over the 7th floor [ I think it was 7th could have been lower] also if it springs a leak you have problems so ask abot this aspect before you purchase, presume said friends would know most of the answers.Sweet dreams I know if you cant sleep anything is worth a try.
does it come with a puncture outfit ? how much money are we talking ? we have the beds that go up & down with half memory foam and half sprung mattresses [ all memory foam gets too hot for us] and they were pricey but we do get a good nights sleep.
You can buy puncture kits for them, the water mattress is in a liner on the bed sides, I have 8 cats and they have not punctured it yet, (speak to soon) I paid £1,000 for mine from aquaglow but I did go for the best one at the time, I bought my daughters from ebay paid £250.00,
