Hi Kopavi,
There are a couple of discrepancies in this listing which would give me reason to pause.
The first of these is that the foam densities given don’t match Talalay latex but they do match Dunlop latex.
Their soft translates to 65 kg/m3 which is soft Dunlop (talalay is lighter than this)
Their medium translates to 75 kg/m3 which is medium Dunlop.
Their firm translates to 85 kg/m3 which is firm Dunlop.
So either their description of the material being talalay is wrong or the densities are wrong (and since they have the specific densities that were probably provided to them … I would guess that it’s Dunlop.
This isn’t bad or good … some people may prefer dunlop. It just indicates that the description isn’t accurate in at least one major way and that customers would probably never know because very few people would even know what to check.
In addition to this, if the latex is zoned … it’s almost always (not always) dunlop
If it’s Dunlop and if in one way or another it’s been mis-described in ways that 99.9% of customers would never know or realize, then is there any way to know if it’s blended or synthetic Dunlop (lower price, quality, and performance)?
Regardless of this though … even if it is Talalay it would not match the PLB Beautiful in terms of feel and performance. The most critical comfort layer has a different thickness in the PLB (3" vs 2") and thickness is just as important as ILD in the feel and performance of a mattress. The PLB has what may be a similar middle layer (although the eBay listing says medium which is not 23 - 26 ILD) and the PLB has a 6" firm support layer while the eBay mattress is only 3". Again layer thickness plays just as important a role as layer ILD.
In addition to this the eBay picture does not match the description which says it has a velour cover (likely fairly cheap) and not the quilted cover shown in the picture (which was probably taken from another mattress) and the PLB has a very high quality more expensive and thick stretch knit cover.
All of these differences would change the comparative feel and performance of the mattresses. This is not to say that the eBay mattress wouldn’t work for a particular person in terms of PPP (Pressure relief, Posture and alignment, and Personal preferences) … only that it wouldn’t be the same as the PLB.
Of course this is just the obvious part. Without knowing the people behind the site … there is really no way to know who they really are and/or how accountable they may be or what other discrepancies there are. Again … when prices are cheap and people believe that what they are getting is good … then the feedback is also good regardless of what they actually receive. In other words there is no way to know them through “real world” reputation because there is no physical address.
If you are comfortable with all of this and it is still inside your “value equation” … then it may be good value for you. This would be a good price even for 100% natural Dunlop but for blended or synthetic Dunlop I would have my doubts. If it is mis-described in several ways already … then who is to know what the rest of the truth is.
This is part of the risk of dealing on outlets like eBay unless you really know who the seller is and whether they have a reputation outside of the eBay community (which would be more important to me).
So while I can’t answer the ultimate question of whether any particular person should go in this direction (which would depend on their risk tolerance and on whether they were OK with unknowingly buying a different mattress or materials than is described) … I hope at least that I have given you some food for thought
