I hate to admit but I may have been conned in carpet installation (stores)

[Mystery123]

If you have noticed my other thread, I paid for 52 or 55 oz carpet with 8 lb pad from Direct Factory Carpet.

Today, I was removing old carpet from bathroom as I want finish that myself and noticed old pad is much thicker than the new one that I have few pieces left.
I haven't weighed them or anything but the new pad looks really light and less than 3/4 thickness of the old one.
Here is a picture.
New pad pieces are on the left and right and old pad is in the center.
I'll take both pieces to local stores and see what it matches with.
What do you think?

I did a google image search and found this:

Residential cut pile, cut- loop, or high-level loop carpet requires a resilient, firm cushion with a thickness of 7/16 inch and no less than 1/4 inch with 6 pounds per cubic feet density. Types of cushion may be various polyurethane foams, including the very common bonded foam product often referred to as “rebond,” fiber, or rubber.
Berber carpet or thinner loop or cut pile carpet is made with large, wide loops, and it has been found that a stable, low-flexing, cushion foundation is necessary. A thicker, softer cushion is not acceptable. Cushion thickness should not exceed 3/8 inch for these type products. Again, check with the carpet manufacturer to see if a specific cushion is required.

Selecting The Right Cushion




Bonded polyurethane foam (sometimes called rebond) is quite unique. You cannot mistake it when you see it, because it is formed by combining chopped and shredded pieces of foam, in different sizes and usually different colors, into one solid piece. It frequently has a surface net for ease of installation and improved performance.
Bonded foam is one of the most amazing recycling projects of all time. Nearly all the scrap foam in the U.S., and some from other countries as well, is utilized to make bonded cushion. This recycles waste, which would otherwise be thrown out, and it eases the strain on our landfills. Moreover, bonded foam is itself recyclable.

In simple words, thickness is not quality. Most of the new carpets, except berber, require a 7/16" or thinner pad. It needs to be of a 6 to 8 lb density. Back in the 80s and 90s they sold a thicker, softer pad. But found out that the carpet did not wear as well.

Thanks for comments.
I'm not questioning quality.
I paid for 8 lb pad so I should get 8 lb pad and this doesn't feel like it's heavy pad compared to old pad.
I think the old pad cannot be over 8 lb as I haven't seen any one offering over 8 lb pad and the new pad is very light and thin.

Old pad looks like bonded foam.

Google image won't help as same pad comes in different weights.

Most of the rebond pad sold in the 80s and 90s was 5/8" 4 lb.

This was built in 1993 and the foam pad is very thick.
I compared to Homedepot sample and it's even thicker than HD's thickest foam pad.

Anyways, I give benefit of the doubt and consider it is 8 lb as I saw thinner pads also weigh 8 lb depending upon how compressed they are so it's good for now.
Thanks all.
