Memory foam is a bit tricky when trying to “duplicate” a mattress as even different varieties of memory foam in the same density will have different feels (speed of recovery, breathability, warmth, and temperature response). The layers above and below the memory foam can also make a big difference in feel and performance as well when duplicating a mattress even though most mattress shoppers don’t pay as much attention to this as they do the memory foam itself when they are testing a mattress as a whole. This means that a memory foam mattress that is similar in construction to another but uses different types or “varieties” of memory foam may offer equal pressure relief, spinal alignment, and long term comfort, even though they may “feel” (a subjective preference) different.
The closest to this particular configuration I know of from an outlet that I know provides good quality foam, options, and value is this one http://www.rockymountainmattress.com/thecoolcomfort10-p-78.html . It has the advantage of being able to re-arrange both the memory foam layers and the support layers to fit your preferences if necessary. The support layers here use 1.8 lb foam (tempur uses 2.2) and doesn’t have the “air channels” but the Aerus foam is more breathable than the tempur and the Sensus is very high quality.
Some other good online outlets for memory foam that I have had the chance to talk with and confirm that they are offering quality products and a few comments are in this thread
Of course the ideal option would be to test some mattresses at a local manufacturer or retail direct sleep shop as that way you could match the “feel” rather than the layering itself and test specifically for pressure relief and alignment. Some of the factory direct options near Hamilton (within about 70KM) include …
http://www.cjmulhollandmattress.ca/ I talked with a saleslady at one of their stores a few months ago and we had a great conversation and I was impressed with what they were doing. When she suggested I talk with the owner Jim, I did (on 2 occasions) but he seemed completely uninterested in my questions or in sharing any information with me about what they are doing. They are also apparently bringing in Natura latex mattresses which would be much more than a typical locally manufactured outlet so I have somewhat mixed feelings about them at the moment … although they may have good value and would probably be well worth a visit since they are so close.
http://www.bbbedding.com/Affiliated-Locations.page Factory direct manufacturer that offers a range of different mattresses and materials.
http://www.qualityrestmattress.com/store_info.htm Factory direct manufacturer. Seems to make primarily innerspring with polyfoam mattresses.
http://www.sleepfactory.com/welcomep.htm They are a franchise group and the knowledge and service of the various outlets will vary from store to store. They are no longer manufacturing mattresses and carry a house brand that used to be made by Springwall but is now being made by by Endless Comfort. They also carry some major brands such as King Koil. The person I talked to at their head office seemed too “busy” to discuss the mattresses they carried and said he would “call me back”. Based on their website and my calls … they don’t seem very interested in providing specs for their mattresses althoug some of the individual outlets are very informed and helpful (and will provide their mattress specs).
http://www.bestwaybedding.com/ Factory direct manufacturer. Run by another member of the Mulholland family but they made it clear that they are not connected.
http://www.fantasticsleepshop.com/ Factory direct manufacturer. Makes a range of low - mid budget mattresses. Can custom build including latex but doesn’t carry them on the floor.
http://www.idealmattress.com/contact.html Factory direct manufacturer. They make their own mattresses using zip covers (so their customers can see what is inside) but also carry major brands (which I would ignore).
http://www.ultramaticsleep.com/contact_us.php Focused more on adjustable beds but they also seem to carry latex and memory foam mattresses
http://www.dreameasy.com/products/100-natural-latex Wholesale manufacturer in Toronto that sells through retail outlets. Based on a couple of conversations I have had with them they seem to be committed to producing high quality products. May be worth a call to see if there are any outlets in Hamilton that carry them.
I would probably make a few phone calls first to get a sense of these outlets and how helpful and informative they seem about their mattresses and materials (especially the ones that are a little further away). I would also mention what you are looking for and see how specific they are with their answers or if they only answer with “come into the store” type of answers.
Hope this helps
