Thanks for sharing your experiences and feedback about your London shopping experiences … I appreciate it
I would certainly “allow” and even encourage posting any specifics about your mattress purchase including pictures, prices, and the store you purchased from. The only links I don’t allow are “self promotional” links from retailers or manufacturers. As you mentioned this type of information would certainly help other members in the London area.
I will even add them to the London / SW Ontario list here along with the brands that carry that disclose the quality of their materials (such as PLB and Natura) although of course that would exclude Serta which I wouldn’t consider.
Post #89 here has more information about the pros and cons of different types of mattress protectors. I would tend to use a protector that covers the top surface of the mattress but fits like a fitted sheet and doesn’t fully encase it because it can allow the mattress to ventilate better and is easier to put on and remove unless you have allergy issues in which case a mattress encasement may be a better choice and there is more about these in post #2 here.
Most important of all … it sounds like you did some great research and ended up making a great choice … and I’m looking forward to finding out the details (and pictures).
