Thankful

Hi Finnashank,

As you probably know … there is no way that the base foam would be 7 lb density. 1.7 lb polyfoam possibly but certainly not 7 lb. I would ask them to find out the correct density. If the mattress is 10" thick (so you know there are no missing layers in the description) then there would be no weak links in the mattress.

You can see the quality guidelines I would suggest in post #4 here and there is much more detail yet about all the variables that can affect durability and the useful life of a mattress in post #4 here. The ā€œbestā€ place to use lower quality and lower cost materials in a lower budget mattress that will have the least effect on durability are in the deeper layers of a mattress that are less subject to the mechanical stresses of compression and will have the least effect on the durability of the mattress. If you are in a higher weight range (higher than the low 200’s or so) then a 1.5 lb support layer would have more effect on durability than it would if you have a lighter body type and don’t compress the support layer as much and with your weight it would have a relatively minor effect on durability and the useful life of the mattress.

The quilted top will affect how the mattress feels compared to sleeping directly on latex layers of the same firmness level and thickness. There is more about the effect of different types quilting layers in post #12 here and the posts it links to.

As you mentioned this is an ā€œall latexā€ mattress that uses three different firmness levels of synthetic continuous pour Dunlop latex and the quilted zip cover also has a different firmness on each side so this provides a total of 12 different combinations of layering that can be used to fine tune the comfort and support of the mattress. There is more about how Dunlop compares to Talalay in post #7 here and the post it links to about the different types and blends of latex.

The biggest advantage of a component mattress such as the Freedom would be the ability to fine tune the mattress after a purchase (which can reduce the risk of an online purchase) and having separate layers also gives you the ability to replace a single layer if one of the layers starts to soften or break down before the others (usually the top layer) or if your needs and preferences change down the road.

There is no way to quantify how long any mattress will last for any particular person but if a mattress is well inside the comfort/support range that is suitable for someone and isn’t close to the edge of the range that is too soft for someone 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 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 ā€œbonus timeā€ 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 ā€œmatchā€ 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 ā€œbonus timeā€ or even ā€œextended bonus timeā€ 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.

There is more about the different ways to choose a suitable mattress (either locally or online) that can help you assess and minimize the risks involved with each of them in post #2 here and there is also more about the most important parts of the ā€œvalueā€ of a mattress purchase in post #13 here that can help you make more meaningful comparisons between mattresses.
