It’s easy enough to find short term reports from purchasers of these beds, but i haven’t been able to find any long term reports be it positive or negative. I guess this may be a no news is good news thing?
SleepEz has been making latex mattresses for decades (Shawn is the third generation of mattress manufacturers in the family and they have been in business for over 35 years) and there are many reviews about them in various places around the web. A google search on “SleepEz reviews” will bring up lots of links from this site (from the last year and a half or so) as well as many others.
The other thing I would consider is that the materials and components in a mattress are more important than who makes it in terms of durability and latex is among the most durable of all mattress materials.
Of course the quality of the materials also has little to do with how the mattress will perform in terms of PPP (Pressure relief, Posture and alignment, and Personal preferences) which has more to do with how the materials are layered and the firmness levels and thickness of the layers than with the material itself but with many years of experience behind them … SleepEz is also very good at making suggestions that will “fit” the large majority of their customers.
For sure I can find reviews, but they all appear to be initial impressions and fine tuning reports. I guess teh fact that apparently nobody is coming back after a few years and saying they are having problems is a good thing. I was hoping to hear from someone who said "the bed worked as advertised for “x” years until it started to lose its feel so I opened it up, changed out a layer and it’s good as new again…
