Hi jfmugen,
[quote]My current budget is capped at about $600, with the top contender being the DreamFoam latex hybrid on Amazon (amzn.com/B00CP85P7I), however I’d prefer something a bit cheaper as I’d have to get a new foundation and sheets along with it
I’m also looking at the DreamFoam 12-in-1 (amzn.com/B00JGBXWVI), which I’ve heard has quality +2 lbs. poly for it’s layers. Does anyone know if this is still true? Because I believe the latex hybrid changed it’s support foam down from +2 to 1.5 lbs.[/quote]
Both of these would be good quality/value options and would certainly be durable choices at your weight (the comfort layers are the most important factor in the durability of a mattress unless you are heavy enough to “go through” the comfort layers and compress the support layers more in which case I would choose a higher density polyfoam support core than 1.5 lbs but you are not in a weigh range where this would be a major consideration).
I don’t know the density of the memory foam in this mattress either so that would be the biggest factor if I was considering this mattress. I would personally tend to choose either the 12 in 1 customizable mattress or the Ultimate Dreams latex because latex is certainly more durable than the memory foam that they would likely be using and the 12 in 1 also uses 2 lb polyfoam which would likely also be a more durable material and has the additional benefit of being able to replace just a single layer instead of the complete mattress if this becomes necessary. While it would depend on the density of the memory foam in this mattress … I would only tend to choose a memory foam mattress in this budget range if cost was the biggest consideration over all the other parts of your personal value equation that are important to you and there was no way I could comfortably afford a mattress that was in a little higher budget range and durability was a less important consideration. I would also keep in mind that this mattress has only a single comfort option which may or may not be suitable for you while both of the other two can be customized to your preferences (the Ultimate Dreams latex before a purchase by choosing the firmness level of the latex and the 12 in 1 after a purchase by rearranging the layers).
My main focus would be on the quality of the materials in a mattress and the knowledge and experience of the retailer/manufacturer and their ability to help you choose a mattress that is a good match for you in terms of PPP. e-comm sites are certainly not your only option if there are also mattresses available to you locally that meet your criteria.
