I bought my hubby some orthopeadic pillows, he suffers with a bad kneck. and they have never gone flat. only drawback is they are quite expensive about £30 each but they do last forever.
Hi Tamaris. Here's a good site here fore more information: http://www.dunlopillopillows.com. I see someone else has advised you to look at the Dunlopillo Range also. All the best!
