Comparing mattress durability

More
11 Jun 2020 19:35 #1 by elle_h
Hi,

I'm trying to assess and compare the durability between 2 mattresses based on construction.  I have a BMI of 20 and a side sleeper.

Mattress A (full size):
cover - organic cotton and joma wool
1.5" quilting foam
3" Dunlop latex
1" comfort foam
6" 700 16 gauge pocket coils with Caliber Edge
1" support foam

Mattress B (full size) flippable:
cover - organic cotton
1" organic wool batting
1-1/4" Dunlop latex
8" 580 13 gauge pocket coils with Caliber Edge
1-1/4" Dunlop latex
1" organic wool batting

Based on what I've read on this site about the durability of the different layers, it seems that Mattress A will be quite durable because of the differential construction of the 3" latex layer, which would take on most of the stress from the innersprings in the deeper layer, and latex is more durable than innersprings.

Mattress B seems to have more durable innersprings compared to that of Mattress A because of its higher gauge, and it is also flippable.  However, it seems to have a progressive construction with a thin latex layer, so the innersprings would take on more wear compared to the innersprings of Mattress A.

Does that mean Mattress A overall is more durable even though it cannot be flipped?

Hello elle_h!

Welcome to our Mattress Forum! :)

I'm trying to assess and compare the durability between 2 mattresses based on construction. I have a BMI of 20 and a side sleeper.


In very general terms, all would depend on the various durability factors which include the type of latex, the softness of the layers, and any other materials in the mattress but if all else was equal and based solely on construction ... then a two-sided mattress will be more durable than the same layers in a single-sided mattress yes ... even with latex. It won't be "twice as much" because all the layers compress in use whether they are on the top or bottom of the mattress but it would make a significant difference IMO. There are always tradeoffs involved though because a two-sided mattress has some design tradeoffs because it can't use thicker softer layers in the comfort layers to the same degree because when they are on the bottom it could affect alignment (it would have the softer layer on one side for comfort and also on the other side which would be part of the support and this can result in higher amounts of softer latex in the mattress).
There is more about one sided vs two-sided mattresses in post #3 .

You are not mentioning the type of foam used in the quilting and comfort layer of mattress A. Without knowing complete mattress details including the density of each of the foam layers it is impossible to say which one would last longer. Even with a complete set of specifications it would be difficult to assess with certainty the durability of mattresses using similar materials because of other qualitative factors such as the way the mattress is manufactured, if it has replaceable layers (Some mattresses have individual layers and a zip cover), glued layers or not, seams, tape edge, and other more “arcane” factors such as the shape of the foam cells, the strength and elasticity of the crosslinks, the resilience of a foam, and the compression modulus, etc… )

The latex components are high-quality materials that are very unlikely to reduce the durability or useful life of a mattress, which you likely learned when you read the Mattress Durability Guidelines but durability is also affected by the firmness of the layers with firmer foam being more durable than softer foam.

A lower gauge means the mattress has a thicker coil, and therefore a firmer spring, but an innerspring isn't normally the weak link in a mattress and the gauge of steel is only one of many factors that determines how a particular innerspring will feel and perform inside a specific mattress design. There is more about the different types of innersprings in this article about innersprings and in post #10 here but I would pay much more attention to the quality of the materials above the innerspring which is normally the weakest link in a mattress.

The "weakest link" in a mattress in terms of durability is normally in the upper layers (the top 3" - 6" of the mattress) that are compressed more deeply when under the weight of the sleeper and not generally in the deeper support layers so the firmer bottom layers of a mattress will have more effect on feel and performance than they will on durability for most people.

I hope this helped clarify some things re durability. Please keep us posted on your mattress purchasing journey!

Phoenix,

Thank you for your always informative responses.

In Two sided versus one sided mattresses , you mention componentized mattresses also allowing for prolonged mattress life. I've read that mattress layers should be secured together (with glue or tufting), to make it durable. For mattresses that have components that could be switched out, isn't that a trade off then?

Hi elle_h.

You are welcome! :)

Not necessarily. You cannot change out the worn layers of a mattress that have been glued or sewn together. When a layer breaks down, you have to replace the entire mattress. With a mattress that has components that can be switched out or replaced, you can ultimately replace a single layer down the road, extending the useful life of the majority of the mattress.

There are benefits to both sides. Gluing and finishing a mattress can make a little more "stable" mattress that is tighter around the foam and can shift or bunch a little less and the layers act a little less independently which can create a little firmer feeling. The sides of the cover can also be re-inforced and it may be a little stronger than a zipper cover. It may slightly increase durability "in theory" although it's questionable whether the difference with a material like latex would be enough to make a significant difference in real life. In some cases, a local manufacturer can open up the mattress and change out a layer if necessary if they leave the layers loose or at least wait with gluing until the final layering is confirmed. In some cases even the quilting and ticking can be glued to keep them from stretching over time.
