Hi ldr3,
[quote]Is it possible to down size a king 100% latex mattress to a queen by cutting the pieces?
If yes what tools would I need? Is a glue available?[/quote]
As long as you aren’t making horizontal cuts to “slit” the foam into a different thickness which would generally need specialized equipment that you would normally find at a mattress manufacturer, a foam fabricator or supplier, or perhaps a fabric or upholstery store … it’s not difficult to cut foam to size using an electric knife and all you need is an electric carving knife and a straight edge for a guide and just go carefully and slowly and move the knife in one direction (not a sawing motion). The length of the blade should be longer than the thickness of the layer you are cutting. You can also see some pictures here of a home setup that was used to make some more complex cuts using an electric knife.
I don’t know what type of cover you have or whether it has a zipper but it would need to be removed as well and if you change the size of the foam layers in your mattress you would also need a new cover. Some of the better online sources for replacement covers I’m aware of are listed in the mattress component list here and there are also a couple of sources for spray glue that can be used to glue foam layers together if there isn’t an upholstery shop or a foam supplier near you that carries it. There is also some information in the mattress surgery topic here that may be helpful as well.
