Adidas Addict:
I went off recommendations from friends that have them, I still think what you say is true of the divan packages etc that the argos et al make up silly RRP's for but just because a company makes budget products for mass market does not mean they don't make decent stuff too. I'll let you know in a few years how I'm getting on with it
Believe me, I'm in the trade, and I refuse to sell any product in the Silentnight group. This includes Silentnight (obviously), Sealy, Rest Assured, Layezee, and The Pocket Sprung Bed Company. The most unreliable thing seems to be the Miracoil continuous spring system (also known as Posturetech by Sealy), but the unreliability problem seems to effect the whole range.
I just hope you are lucky with yours.
