[quote=“Phoenix” post=590]Hi Lisa,
Foamex (now called FXI) is a company that manufactures polyfoam and memory foam. They have a rather unique method of manufacturing foam called VPF which produces very high quality foam IMO. They make a memory foam called Aerus which is a more breathable and cooler version of memory foam. While a more “open celled” foam is also manufactured by other foam producers using various chemical methods, holes in the foam, air channels, and gel infusions … the Aerus is among the most breathable of these. It is normally seen in 4 lb density in places like Sams Club and Walmart … it also comes in 5 lb versions that is used by some manufacturers and is alos available in toppers. They also make Sensus memory foam which is less breathable and slower responding but is also a very high quality memory foam.
Since the Sams Club and the Amazon mattresses are using the same Aerus memory foam (made by Foamex), and the Sams club has a thicker layer of polyfoam underneath it (which will likely make it a bit softer overall) and it is also a lower cost, and has a free return privilege, … the Sams club is clearly a better value IMO.
The Night Therapy brand is made by Zinus which is a Chinese manufacturer which is CertiPur certified. They don’t list the density of the memory foam which could be either 3 or 4 lbs (Zinus usually is in this range). I would choose Aerus over this even if the night therapy was 4 lb even though the Night Therapy is a little lower. I would not buy any 3 lb memory foam at all.
The Novaform gel memory foam at Costco is a lower density version of the gel memory foam in the iComfort. I roughly calculated it to be about 4 lb overall so it doesn’t surprise me that you were told what you were told. It is basically a lower quality memory foam that is infused with gel (which weighs more than memory foam) so it will “act” and “weigh” more like a higher density foam. While the gel may work to cool down the foam somewhat (just like a countertop feels cooler because it draws heat from your body) … I have not seen any evidence that it actually has that big an effect in real life. It is also true that the heavier gel makes the foam seem denser than it would be without it however it is still lower quality memory foam with heavier gel infused in it and will likely suffer the same or similar early breakdown that is part of low density memory foamss in general. I personally would choose the Aerus over the gel memory foam as I believe it has better value. Having said that … the gel does make it “act” a little different so some people may prefer its feel.
If there is a local manufacturer near you (I posted an LA list in the previous post) that offers 5 lb foam this will often represent your best value as you can test to see exactly how it fits your circumstances in terms of pressure relief and alignment rather than having to “guess” with an online memory foam outlet.
Some of the online choices in this thread (particularly post #4) may also be worth considering. While they are higher in price than the Sams Club Aerus … they also in some cases use higher quality memory foam (5 lb or higher) and/or in other cases give you the opportunity to adjusts the support layers under the memory foam to “fine tune” the mattress to your needs.

Hi Phoenix,
Thank you for your response. I ended up trying the Ortho from the store and they had a 10in memory foam and felt good but the price was out of my range. So I ended up ordering the one from Sams Club just because of their great warranty. I tried out the bed last night and my back is hurting…is there a break in period?
Also I am checking out the one you mention from https://www.flexuscomfort.com/. They have a special for Cal King for $500 for the set. They indicated they have 5lbs memory foam but is only 8.5 inch thick.
I have a few questions:
- Would it be a better bed if I got the https://www.flexuscomfort.com/ and returned my Sams Club one?
- Is there a difference between 12 inch (Sams Club) vs 8.5 inch (https://www.flexuscomfort.com/)
- Is there a break in period for memory foam
Thanks again Phoenix for all your help.
