Hi Phsical70,
I do like Aerus memory foam but before I considered this mattress (or any mattress) I would want to know the density of the base layer. It’s likely to be in the 1.5 lb range which is low quality and would not be as durable as a higher quality base layer. You can see the memory foam criteria I use in post #10 here.
I’ve also noticed that some of the big box stores haven’t been accurate in some of their listings as you can see in post #2 here.
I think that the one good thing about the big box stores is their return policy and they can also be a good option for someone that can sleep on anything and where the suitability of a mattress for their needs and preferences isn’t as important. Other than that though you would be making a purchase based on the luck of the draw and your willingness to keep returning mattresses until you find the right one because they certainly don’t have the knowledge to help their customers choose the most suitable mattress.
I think highly of both of these although they are all very different and not directly comparable.
Design sleep has a whole range of mattresses including latex, innersprings, and microcoils. They are knowledgeable and helpful, have good value, and are well worth talking to and visiting if you are near them. Because they are local you can test them in person which to me increases the value of a mattress vs an online purchase and I usually use a guideline of about 20% or so to reflect the added value of a local purchase vs the extra risk involved in an online purchase.
Mygreenmattress is a member of this site (like Brooklyn bedding and Mattresses.net and others) which means I believe they are among the best quality and value in the country. Every person that has gone there has commented on the exceptional knowledge and service they have received. Their latex mattresses are a little unusual in that they are two sided which add to their value as well. They are also mostly local in the Chicago area but they also ship their mattresses anywhere in the country and would also be well worth talking to.
I would guess you are getting a false positive and I wouldn’t hesitate to visit their site (and their Quality Sleep Shop sister site) … or for that matter to buy a mattress from them,
Mattresses.net has a strong focus towards latex itself (of all types in both natural and blended) although they sell other types of mattresses as well and they are one of the few (and among the first) to carry organic Dunlop latex. I would think it’s fair to say that many people looking for natural or organic latex would buy from them because of their knowledge and the value of their products but I would say that their main focus in providing high value choices in all the types of latex that people may prefer which of course includes natural latex.
Brooklyn Bedding tends more towards hybrid mattresses (latex or memory foam exchangeable comfort layers over polyfoam) but also has other options including an all latex mattress as well. Most of the latex they sell is blended Talalay (some include natural Dunlop as well) and their focus in on the online sales of high quality and value mattresses that have a very flexible design more than a larger selection of many different types of latex.
Hope this helps.
