Hi guys further to my previous email,I have now purchased the previously mentioned mdf sheets ,and it has made an enormous difference to my sleep,just wonderful,and the matress also looks so much better too without that mid bed sag, One thing though is that mdf is definitely NOT 3mm,that would simply snap,if you buy it at that gauge,it very definitely must be 9mm,I paid approx £6 for my two pieces and well worth the outlay.

The other thing I was wondering about,is that I think I mixed up a matress topper with ties/tapes so when my new matress arrives I will just trial it and decide what to do with my mem/foam matress later,sorry for being so long winded,and thanks once again.Alan
