Hi josie,
There are a few differences in the Woodlawn from the other options you are considering that would make a difference in how the mattress feels and the value of the mattress.
First it is two sided and finished on both sides which means it can be flipped which can extend the life and even out the wear or compression of the upper layers and the wool fiber. Two sided construction is a “value added” option because it has a comfort layer and is finished on both sides which of course costs more than a one sided construction.
It uses an inherent fire barrier which means the wool layer doesn’t have to be compressed as much and it is also a loftier wool finish (tack and jump vs quilted). Even though they don’t say the amount of wool used … it appears to use more and the wool also has more loft (which would make it a little softer) and is finished on both sides.
The comfort layers are 1.5" and the closest alternative would be about 2" which would be a little softer if the ILD was similar so this will also make a difference.
ILD is approximate in Dunlop so it may also not be an exact match for either the “soft” or “medium” Dunlop (or Talalay) used in the core layers in the alternatives you are considering. The firmness level of the core layer will also affect the pressure relief properties of the upper layers more when they are thinner.
If you described or showed the specs of the Woodlawn to one of the online manufacturers you were considering and they had this information along with your impressions of the mattress from your testing … they would be in a better position to recommend the model they make which would be the closest approximation.
At Parklane, unless you were also considering ordering from them without testing the mattress, I would go by how similar it felt with your testing which is more accurate than going by “specs”.
I personally place a premium on purchasing a mattress that you have specifically tested and know it works well for you in terms of pressure relief, alignment, and your preferences. While each person will decide for themselves which features they place the most value on, I think a “premium” in the range of 20% for a local purchase compared to a similar layering and construction if that was necessary may be worth the additional “safety” of a known purchase. If the premium was more than that … then I would probably consider the additional risk of an online purchase. How much additional risk there would be would depend of course on how similar the online purchase was and the options you had to change around the layers or make exchanges after the purchase. This is also just a guideline because of course each person would need to weigh out the pros and cons of their various options based on their own personal “value equation”.
Over the very long life of a latex mattress … and considering the importance of a mattress in your overall wellbeing (it’s by far the most important piece of furniture that people own) … a reasonable premium is a small price to pay for “getting it right”.
In the end, if the difference in value (not just price) is small, then I would happily pay a reasonable premium for the knowledge that a mattress was exactly what I wanted.
