unhappily the Sherwood EvoSleep biomedical gel RX300 mattress I purchased Aug 2013 developed hammocking and I will need to replace the mattress. the store from which i purchased the mattress will allow replacement for equal or better (and i pay any difference in price). so now i am starting all over to find a new mattress – this must be done within 2 weeks. does anyone know anything about the Sherwood Dunlopillo Ambiance Luxury Firm?
I’m sorry to hear that your mattress didn’t work out for you and that you need to replace it. The good news is that the visible impressions in your mattress were deep enough that you were covered under the warranty.
You can see the individual layers of the Dunlopillo Ambience here but they don’t mention the thickness of each layer or the density of the polyfoam layers so I would make sure that you find this out (especially with the upper layers of the mattress) so that you can identify any weak links in the mattress.
They should be able to provide you with the information you need (see this article) and if you can post it on the forum I’d be happy to make some comments about the quality of the materials inside the mattress.
