Hi Phoenix,
So I decided to do the same calculation you did in this post with the Regalis Luxe. This would be another data point which we can use to determine whether Select Foam’s listed attributes are accurate.
Unfortunately, the results are inconclusive:
The weight of the Regalix Luxe Queen size mattress should be:
Top layer = 60 x 80 x 1.5 / 1728 x 7.2 = 30lb
Middle layer = 60 x 80 x 2.5 / 1728 x 5.3 = 36.8lb
Bottom layer = 60 x 80 x 9 /1728 x 1.8* = 45lb (note that the bottom layer density is not listed on the website, so I’m using your 1.8lb density estimate from the above linked posted)
Total weight = 111.8lb
Now this is where things get weird. The weight according to the law tag is 62.7lb, and the weight according to FedEx is 133lbs. 62.7lb seems way too low to be accurate to me, so I’m inclined to think the true weight is maybe 130lbs if you deduct a few pounds for packaging from the FedEx weight. The remaining ~19lb variance could be due to the bottom layer being denser than 1.8lbs.
So this seems to support the claim that the law tags are wrong. The only thing that seems suspicious was when I measured the individual layers on the mattress; the top layer was closer to 1" than 1.5". Probably not enough to get upset about though.
Please let me know if you see anything off about my calculations/conclusions!
I’ll still try to get a picture of the law tag for the Cirrus Luxe before they send it when I speak with them tomorrow.
