Hi NJRonbo,
Welcome to the Mattress Forum! 
I understand your frustration with the many “review” sites that are in fact “revenue” sites, and it’s not limited to any one specific brand. A big part of the underlying problem with these types of marketing systems though is that consumers as a whole put too much trust in mattress reviews in the first place (either positive or negative) in the mistaken belief that they are a good way to assess whether a mattress would be a suitable or a durable choice for them so they end up choosing a mattress for all the wrong reasons based on other people’s experiences and reviews or on the “deal” they think they are getting instead of legitimate “fact based” research that would be relevant to their own unique needs, preferences, and criteria. This is more of an issue with consumers in general that can really only be solved with education about how to buy a mattress but because reviews have become so important in today’s online market they have gained a false aura of legitimacy and while they may not be the cause of the problem … many mattress companies are well aware of their ability to influence people and change buying habits and certainly take full advantage of the mindset and target market that pays significant attention to them so they are really just taking advantage of a “reality” that they know will sell mattresses for them.
While most reviewers are certainly well meaning … because most reviews aren’t relevant to anyone but the reviewer and can be “influenced” so easily and in so many ways … for the most part (with only few exceptions) mattress reviews are a classic example of garbage in / garbage out even though the “garbage” may be well meaning and true to the experience of the person writing the review. In many ways it reminds me of MLM companies which turn customers into salespeople where people will say whatever they need to say in their “testimonials” in order to sell their products and their business to others.
The real solution to the problem IMO would be to change the consumer mindset that places undue importance on online reviews in the first place which is the engine that drives these types of marketing systems along with the paid review services that will write online reviews for you for a fee as well so you can claim to have the “best reviewed mattress” which too many people believe translates into “the best mattress” when it doesn’t … but this is unlikely to change anytime soon.
Latex is certainly a very durable material, and it is quite point elastic. Whether or not the Luxury Plush side of the Zen Haven will be comfortable enough for you on your side can only be determined through your own personal testing once you receive the product.
It seems dichotomous to me that you complained about reviews in the first part of your post, yet you ordered a new mattress based upon reviews from the very company you stated you didn’t like because of how you feel the same company handles and courts online reviews. Especially as there are a myriad of other online latex mattress sources. There’s of course nothing wrong with choosing the Zen Haven, as it uses good quality and durable materials. I just find the choice interesting based upon your statements.
As alluded to previously regarding reviews, there are too many unknowns, variables, and personal preferences involved in choosing a mattress for someone else to make specific suggestions based on specs (either yours or a mattress) or theory at a distance that can possible be more accurate than your own careful and objective testing (using the testing guidelines in the tutorial post) which is always the most reliable way to predict which mattress will be the best match for you in terms of PPP (Posture and alignment, Pressure relief, and your Personal preferences) (see mattress firmness/comfort levels in post #2 here), and reviews or other people’s experiences in general just won’t tell you much if anything about the suitability, quality, durability, or “value” of a mattress for any particular person (see post #13 here). Hopefully you’ll report back that your new mattress is working out well for you. :cheer:
You always need to use some sort of mattress pad or protector over your mattress. While certain products may be dust mite resistant, if the food source and environment are appropriate, you can get dust mites in any style of mattress. The key things would be keeping their main food source (skin cells) to a minimum, and keeping the environment low in humidity (they prefer a warm, moist environment). There’s some good information about mattress protectors in post #89 here, and this post.
I’m looking forward to learning about your new mattress once you’ve had a chance to sleep upon it for a while.
