Hi shadesofgrey,
Unfortunately … the most important specs are missing which is the density of the polyfoam in the mattress. There are really only three types of foams which are latex, memory foam, and polyfoam. Conforma foam is a zoned convoluted polyfoam, soy based foam is a polyfoam, and ecotex is also a polyfoam. It’s always pretty safe to assume that if it doesn’t say memory foam or latex then it’s polyfoam and then it’s important to know the density which determines the quality and the durability.
The specs are also missing the layer thicknesses so it’s not possible to tell how similar the the Peyton and the Bisque may be. For example one could have several inches of latex and one could only have 1/2 an inch although they very well could be similar because house brands are often less than the National brand made by the same manufacturer.
The most important part of shopping for a mattress is to make sure that the outlet is able to give you all the information about the layers in their mattress or it becomes impossible to know what the weak link (the part that softens and degrades first) may be or how it compares in value to other mattresses.
Restwell is a spring Air licensee in Vancouver and while they make some nice mattresses, they are not always transparent about their materials and they can be somewhat overpriced.
Some options that may be worth considering …
renelle.com They are a Surrey based wholesale manufacturer that has a very nice line of memory foam mattresses and in the next couple of weeks a new line of latex mattresses will also be in the stores (UPDATE: These are now available). If you call them they will give you the name of any local outlets that carry them.
http://foamandhomedecor.com/foam.php Surrey. They are a foam distributor but will make a mattress to your specs. Unfortunately they don’t have finished mattresses available for testing.
http://www.manta.com/ic/mtqdg82/ca/jordan-mattress-ltd They are a Restonic licensee and make a full range of mattresses including latex which may have some better value (depending on the retail outlet). A phone call would likely give you the names of any local retail outlets that carried them.
NOTE: there is a more complete list of Vancouver area options in post #2 here.
If you can get the foam specs (density of the polyfoam and type of latex) and the details of the layer thicknesses for the Restwells it would be easier to make more meaningful comparisons between them and also other mattresses.
