Sleep Science 9" King Latex GL on sale at Costco

[phoenix]

Hi LatexQuest,

My first post…but looking for some advice. I’ve done a tremendous amount of research on mattresses and I’m leaning towards a Latex mattress. Really appreciate the site and forum here as it has been extremely helpful.

My wife and I both went to the store and we really liked the Serta iComfort Savant Everfeel firm. We have a pillowtop now but are both looking for the firm support. The mattress we are comparing that with, is this one on the Costco website. www.costco.com/.product.945280.html

These are very different mattresses and aren’t really comparable and are about as different as two foam materials can be. The Serta iComfort Savant Everfeel is a memory foam mattress and the Sleep Science is a latex/polyfoam hybrid. There is more about the differences between memory foam and latex in post #2 here.

Wondering if you have thoughts on the Costco mattress. It lays out the layers pretty well and the ILDs seem to add up to a good comfortable mattress. Also, it says GL in the title, but not sure if that is the quick or slow response.

The mattress has 4" of latex on a polyfoam base. They don’t specify the density which I would want to know but assuming the density of the base layer is suitable then there would be no weak links in the mattress.

My biggest concern here would be with "value. The mattress by itself sells for $2199.99 which would be very costly for this type of mattress compared to other latex/polyfoam hybrid mattresses or even some all latex mattresses that are sold by some of the companies listed in posts #3 and #4 here. The Talalay GL would be fast response (they don’t make Talalay GL slow response any more).

When this mattress was on sale at $1699 I didn’t think it was in the best value range (see this topic) but at $2299 the “value” would be even worse compared to the other options you have available to you.

My other option is just going back to Sleep Country and getting them to bring down the price of the iComfort as I do think it would be a good mattress.

I would avoid the major brands and the bigger chain stores or any mattress where you aren’t able to find out the quality of the materials inside it (see the guidelines here). This would be a very risky purchase.

Hopefully you’ve had the chance to read the mattress shopping tutorial here which also includes two links to lists of the better online options I’m aware of (in the optional online step).

If you let me know your city or zip code I’d also be happy to let you know about any of the better options or possibilities I’m aware of in your area.
