Hi atopic,
Medium Firm (34) High Resilience Foam (3.0 lb). I assume the figures in parentheses refer to ILD and density, respectively, although the latter figure could be weight.
The 34 would be the ILD, and the 3.0 lb would be the density (mass per unit volume, on in this case one cubic foot weight).
Also, if you refer to their Foam Density and ILD Chart, it gives a figure of 2.8 lb and of 3.0 lb for density of High Resilience Foam, depending upon firmness...?
Density and ILD of polyfoam aren’t directly correlated, so it shows that they offer two different densities of HR polyfoam, but I’m not familiar with their current stock and what densities that they offer in the various ILDs. You’d have to phone them for that information, which I would recommend regardless before placing an order with any foam supplier.
My unease comes in when I look at the spec's you refer to in their "descriptions" link, which give ranges for density and ILD, rather than specific values. Does this mean I could be buying 3.0 density foam and actually receive 2.5 density foam? Does it matter?
The density does of course matter, but there is always some variation (it isn’t exact). But if you ordered a 3.0 lb density foam you’d expect it to be close to that and not 2.5 lb. ILDs are also not exact numbers, but better described as ranges, which is why they state on the ILD chart that they’ll ship the closest to what is listed on their chart for the “word descriptions” of the foam, which is often a better way of describing things.
I personally would have no unease, and in this situation I see a company that’s actually doing the opposite of most brands and taking the time to provide more specifications about their products than you normally find. But I would place my order over the phone versus online to make sure you’re going to receive the type of product that you desire.
While both companies got an A+ rating on BBB (despite several complaints), the complaints against Foam Online seemed more damning when it comes to foam quality; i.e., not living up to promise. For what it's worth...
I wouldn’t agree – I don’t find the complaints to be damning. One person said they ordered extra firm memory foam (all memory foam will be soft) and they obviously confused it with another foam on the web site (or aren't familiar with memory foam), another seems to be confusing HR polyfoam with memory foam, another received their product in the timeframe specified but apparently didn’t like the “tone” of an email or being placed on hold, another had an item out of stock and had their purchase refunded, another had confusion about an extra firm memory foam again (a refund was issued), and a final one seems to be about an order that shipped late.
I’ll admit that their website ordering interface is probably responsible for a few of these complaints/confusions, and that the owner isn’t exactly a wordsmith with replies, but I personally wouldn’t find any of this a cause for concern.
