I'm looking for a custom size mattress for an antique bed. Of course we would like to try it for comfort so buying at a local store is a definite plus.

The only brands that I can find locally in the NYC-LI area that will supply a custom size are King Koil and Corsicana. They will make up a 42" King Koil for the price of a Queen size, which seems reasonable. The Corsicanas go for about 25% more, and there is a Corsicana line (Ascot) with pocketed coils.

But net reviews of these brands are very spotty.

Any comments on these brands, or good choices within? Is there any other brand with national distribution that will make up a custom mattress?

Thanks.
