Hi Peaches28,
Welcome to the Mattress Forum!
You’re welcome.
I believe they use the Leggett and Platt Quantum Edge Combi-Zone for the innerspring unit in the Premier, which is a good quality innerspring unit. On top of that is 1" of natural Talalay latex, and beneath that is 1" of natural Dunlop latex. These would all be good quality and durable materials, and whether or not they would be “enough” would come down to your own personal comfort preference. There’s certainly nothing “wrong” with a mattress using thinner comfort layers, especially on top of a pocketed spring unit, and some people do prefer it. And a ¾" is a pretty standard impression limit for mattresses containing latex (1.5" is more common for mattresses using polyfoams).
It’s a good quality edge system and can be more durable (and bendable) than the foam encasement system it replaces.
I’m not sure what “opinions” you’re looking for, unless you’re referring to the more objective questions about the componentry used within the mattress, which would be the most important facts for you to acquire. The most reliable way to assess the quality and durability of a mattress regardless of the name of the manufacturer on the label is to make sure you know the type and quality of all the materials inside it so you can identify any lower quality materials or weak links in the mattress. Kurt Ling, one of the principals of Posh + Lavish, was also one of the founders of Pure Latex Bliss (now Pure Talalay Bliss).
Sleeping prone with a BMI in that range would generally require a bit “firmer” of a surface comfort, so I think you are considering appropriate options.
Mattress companies will tell you, “There’s a reason chairs were invented.” :lol: Sitting on the edge of a mattress, regardless of the quality of the edge system, will cause excessive wear in that area. The edge reinforcement system is primarily there to minimize product roll-off when sleeping close to the edge of the product.
While it’s not possible to quantify how long any mattress will last for any particular person, if a mattress is well inside a suitable comfort/support range and isn’t close to the edge of being too soft when it is new and meets the minimum quality specs that are suggested in the guidelines here then it would be reasonable to expect a useful lifetime in the range of 7 - 10 years and with higher quality and more durable materials that are well above the minimum guidelines like latex or higher density memory foam or polyfoam (in the comfort layers especially) it would likely be in the higher end of the range or even longer.
It’s always more realistic to think of about 10 years as a maximum reasonable expectation for any mattress no matter what the quality or durability of the materials and then treat any additional time after that as “bonus time” because after about 10 years the limiting factor in the useful life of a mattress will often be the changing needs and preferences of the person sleeping on the mattress and even if a mattress is still in good condition after a decade … a mattress that was suitable for someone 10 years earlier may not be the best “match” any longer.
Having said that … with higher quality materials throughout a mattress and/or for people whose needs and preferences or physical condition or body type hasn’t changed much over 10 years then “bonus time” or even “extended bonus time” with higher quality/density and more durable materials like latex or higher density memory foam or polyfoam or natural fibers is much more likely than with less durable materials.
