Hi Ptery83,
Hopefully some of the other members that have purchased there will see your post and comment about their experience.
The Mattress Factory is one of the members here which means that I think very highly of them and that I believe they compete well with the best in the industry in terms of their quality,value, and service.
There is also more about the most important parts of the “value” of a mattress purchase in post #13 here that can help you make more meaningful comparisons between mattresses. Outside of PPP (Posture and alignment, Pressure relief, and Personal preferences) the most important part of the “value” of a mattress purchase is the quality of the construction and the durability of the materials inside it regardless of the name of the manufacturer.
Your own testing will tell you more than anything else or anyone else’s experience about whether a mattress is a suitable match for you in terms of PPP (a mattress that is “perfect” for one person may be completely unsuitable for someone else to sleep on) and I would be very cautious about using one person’s or even a group of people’s experience on a mattress as a reliable guide to how suitable a mattress may be for you (see post #13 here). Knowing the quality of the materials inside it (see this article) will tell you about whether the mattress has any weak links in terms of durability and the useful life of the mattress.
I’m looking forward to your feedback if you do decide to pay them a visit :).
