Where to buy adjustable base / foundation / bed online?

Hi Cobalt,

I switched your post to a new topic of its own so your questions don’t get mixed in with a different set of questions from another member.

It has been 20+ years since I had to shop for a matress (ugh!). I’m looking into memory foam or latex matresses and would like to also purchase an adjustable bed frame. This site has been very helpful! One of the manufacturers I visited stated that for the flexible base a latex bottom layer is the best. (Seems to make sense since it is rubber). But if I end up choosing a matress with a non-latex, high density foam as the bottom layer, does it really make that much of a difference?
He also said for best comfort/flexibility the matress should be no more than 10 inches. I like a higher bed. Again, if matress is 12 inches, would that really make a noticeable difference?

In general terms most foam mattresses (memory foam, latex foam, polyfoam) that aren’t more than about 12" thick and most pocket coil mattresses will be flexible enough to work well on an adjustable bed but when you are over about 12" thick then the mattress may not contour to the adjustable bed as effectively. While in general terms thinner mattresses will tend to be more flexible than thicker mattresses and will contour to the adjustable bed more effectively … this can also depend on the specifics of the mattress layers and components and staying below about 12" thickness is only a general guideline because some mattresses that are a little more than that which use more flexible materials may still be fine and some mattresses that are less than that may be less flexible and not work as well but 12" is a good general guideline.

Latex is certainly a very flexible material and works very well on an adjustable bed so a thicker latex mattress may contour more effectively than a thicker mattress that uses less flexible foam materials (such as polyfoam) but it’s certainly not the only option you have. The most reliable source of information about whether any specific mattress would be a suitable choice for an adjustable bed will be a knowledgeable and experienced retailer or the manufacturer that makes the mattress.

Last question, for under 130 lb or even 175 lb person, would taking 2 inches off the bottom layer whether latex or high density foam make a difference (taking a 12 or 13 inch matress down 2 inches)? Thanks so much for your thoughts.

Every layer and component in a mattress will have some effect on every other layer and component in the mattress and on the mattress “as a whole” so every change to the design of a mattress will make “some difference” to how the mattress feels and performs for specific people. Whether the difference would be enough for a particular person to feel would also depend on the specifics of the mattress, on the body type and sleeping positions of the person, and on the sensitivity of the person sleeping on it as well. With some mattresses and for some people it could certainly make a noticeable difference while for other mattresses that have a different design but are the same thickness or for people that are less sensitive the difference may not be noticeable at all.

Higher body weights will tend to notice the effect of deeper layers more than lighter body weights and changing the thickness of firmer layers on the bottom will have less effect than changing the thickness of softer layers on the bottom. There is more about the general effect of thickness in post #14 here.
