Hi OPILOVA,
Hopefully you’ve read the mattress shopping tutorial here which has all the basic information, steps, and guidelines that you will need to make the best possible choices. The tutorial also includes a link to a list of the members here that sell mattresses online and many of these make latex mattresses that use different types of latex (including organic Dunlop) and have a range of different designs and options that would also be worth considering or that you can use as reference points for value.
I’m guessing that you mean Habitat Furnishings … is that correct ?
There is more information in post #13 here about the most important parts of the value of a mattress purchase that can help you make more meaningful comparisons between mattresses.
The most important part of value is that a mattress is a good match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) so I would make sure you are confident that a 6" Dunlop latex mattress is a suitable match for you because it would probably be firmer than most people may be comfortable with and if you don’t sleep well on a mattress then no matter what the quality of the materials or what you paid it would have little value to you.
There are no standard definitions of what either “medium” or “medium firm” means between different manufacturers and different people can also have very different opinions about the firmness of any specific mattress. A mattress that is too firm for one person can be too soft for someone else depending on their body type, sleeping positions, and personal preferences and sensitivities. The only way to know for certain whether a mattress feels like a “medium” or a “medium firm” based on your definition of both would be your own personal testing or experience. Latex mattresses … especially Dunlop latex … can also feel firmer than other types of foam materials that you may be more used to so it would also be worthwhile to see if you can test some Dunlop latex mattresses in person if they are available in your area.
A topper can be an effective way to add some additional softness and pressure relief to a mattress that is too firm (see post #2 here) but I would also be aware that choosing a topper that is a good match for you in combination with a specific mattress (different mattresses under a topper can change how a topper feels) can sometimes be as difficult or uncertain as choosing a mattress in the first place and buying a mattress and then adding a topper can also be more costly than ordering a mattress that already has the softer layer inside the cover as part of the mattress itself. I would normally focus on making a choice that has the best odds of being suitable for you in the first place (see post #2 here). In this case though … they also have a good return policy that allows you to return the mattress for a refund with a nominal shipping fee ($75) so this would also be an option that would allow you to return the mattress if it was too firm and then choose a different mattress instead of keeping the mattress and buying a separate topper.
Other than PPP the next most important part of the value of a mattress purchase is the quality of the materials and in this case your mattress uses 100% natural Dunlop (not organic) with a viscose “semi synthetic” (viscose) Aloe Vera cover quilted with wool which are both good quality materials. While wool can be used by itself as a fire retardant barrier in a mattress … they don’t mention whether wool is the only fire retardant used in the mattress or the number of oz/sq yd of wool so if this is important to you I would make sure you ask them because in some cases you will find that there is a smaller amount of wool in a mattress and the wool is used in addition to another type of fire barrier in the mattress (typically an inherent viscose/silica fire barrier). The reason this may be important is that they have recently started offering a wool quilted cover but the prices stayed the same (and in your case there is an additional $100 discount) so I would want to make sure that the wool in the cover is being used in a reasonable amount and is the only fire retardant material so that if you are making more “apples to apples” comparisons to other mattresses that only use wool quilted covers as their fire barrier.
The last part of deciding on the “value” of a mattress purchase would be to compare it to your other finalists based on all the parts of your personal value equation that are important to you because the value of a mattress is always relative to the other mattresses you are considering or that are available to you.
There is more in post #2 here about organic, natural, safe, and green materials (which all have different meanings) which can also help you decide on the types of materials you are comfortable having in your mattress.
So to recap everything … if you are confident that this mattress is a suitable choice for your body type, sleeping positions, and preferences in terms of PPP (without a topper) … and since it uses good quality and durable materials … then if it also compares well to your other finalists (including the wool quilting) and some of the additional features and options that may be more important to others or that are available aren’t important to you (such as exchangeable layers) then it seems to me that for you it could make a good value choice.
