I contacted Juan Quintero from Select Foam and he confirmed that their toppers are 100% natural talalay from Latex International. I was very specific with my question just to be sure; i asked if their topper was actually “100% natural latex that contained absolutely NO amount of styrene or butadiene” and he confirmed that to be the case. He said that their account representative from LI told them that their N3 topper had an approximate 28 ILD and that is what they put on their site, but he confirmed to me that it’s actually a range of 25-29, and that they probably should update/change their website to indicate that.
I contacted Neal from Spindle Mattress per your suggestion and he was able to help me out. He provided me with the compression set and impact test results for the Mountaintop synthetic dunlop in the 18-22 firmness range:
Impact Test:
ILD Loss @ 25% Compression: 5.60%
Height Loss after 10,000 cycles: 0.57%
Compression Set Test:
Height Loss: 3%
I obviously don’t have the experience to know how this translates to real-world performance, but those specs seem ‘better’ than LI blended latex from what i can tell. LI Talatech had a 6% loss in ILD in the impact test and a 3.3% height loss in the compression set test according to SleepLikeaBear’s FAQ (though they didn’t state what ILD/density this was for, so i can’t really compare the test results between the two). Do you happen to have the impact and compression set test numbers for LI’s talatech in 19 ILD?
Unfortunately though, since Spindle Mattress doesn’t have a layer exchange option for their toppers (and they only carry one ILD range for the full synthetic topper anyways), i don’t think i want to take the risk on this product without feeling it in person first, even though it does seem very comparable to blended talalay.
It’s 80% Cotton and 20% Polyester (there’s a picture of the law tag too). It does seem to pretty decently constructed based on the other photos of it there. Wish i could find someone that has first-hand experience with this cover, search results on these forums (using the terms “VELOUR” or “memoryfoamlatex”) didn’t turn up anything. I’m still not sure if i should gamble on this item, especially given memoryfoamlatex’s history with improperly labeled items and their very poor return policy (buyer pays shipping both ways and 20% restocking fee), though Ebay does seem to honor their money back guarantee with this vendor (so if i did receive an item that wasn’t as described i could get a refund through Ebay).
I definitely don’t want to risk my $1000 worth of latex degrading prematurely because i decide to go with a cheap cover. Might be worth the extra $100 to go with the SleepEZ cover.
Yes, that’s what i’m going to do. I decided to go with vendors that have excellent return policies and comfort/layer exchanges. Luckily, Brooklyn Bedding and Select Foam are outstanding in this department and also happen to have some of the cheapest prices on latex too (Select Foam being the absolute cheapest for 100% natural talalay; BB being the second cheapest for blended, after Mattress247). This way i can start off with a ‘safe’ design and fine-tune things with a layer exchange or two (or three).
So I’m going to start off with what i mentioned earlier:
3" blended talalay, 19 ILD, from Brooklyn Bedding for $324
3" 100% natural talalay, 25-29 ILD (LI N3), from Select Foam for $309
3" blended talalay, 36 ILD, from Brooklyn Bedding for $324
Total: $957 shipped for the latex
With either the Velour cover from Memoryfoamlatex for $54 or the SleepEZ 4-way stretch cover for $155.
If need be i can send the Select Foam layer back for free (they even pay return shipping) and then get another BB layer to replace it. All of the BB layers have a one-time, ‘free’ ($50 return shipping fee), firmness exchange, so i can swap those if needed to fix any problems. Overall, i think this is a pretty ‘safe’ design plan, worst case scenario i lose $150 on layer exchanges but at least get to fix any problems in my original design.
