Ikea Laxeby Slatted Base - I don't get the point of the adjustability...

I was going to pick this base up this weekend for my new king SleepEZ, but looking at the design I'm not sure I understand the layout of the adjustable slats.

 

The adjustable slats are just regular slats with a shorter slat attached to the bottom and 2 sliders that hold them together.

If I am understanding the design correctly, moving the sliders to the center takes the extra slat out of the equation and makes the slat the same tension as the non-adjustable ones.

Moving the sliders towards the ends progressively engages the short slat underneath and adds extra stiffness and less "give".

The adjustable "zones" appear to be positioned at the shoulder and hip area.

This doesn't make sense to me... why would one want to stiffen the shoulder and hip zones relative to the lumbar? Wouldn't you want more "give" in these areas?

I initially thought of getting a Euro Slat base ... but after reading the V-Zone product and speaking with Dewey, I think I am going to go for the V Zone bed from Flobeds.

It will achieve what you are discussing Diane ... the support in the right areas and more plushness in the butt and shoulders.  I am 6'5" so when I sleep on my side, there is quite a bit of shoulder to be absorbed by my current S Brand pocket coil mattress.

Interesting discussion ... and something that I talked to many people about (mostly mattress manufacturers at some level) and experimented with by lying on mattresses until it "sort of" became clear to me.

The first assumption is that the best sleeping position is one where the spine is either straight (side sleeping) or follows it's "natural" curve (Back and stomach sleeping). If you imagine someone sleeping on their side on a sheet of plywood, then their hip and shoulder area would be "pushed up" and there would not be enough give in these areas to create a flat spine. On the other hand if someone was sleeping on something extremely soft, the shoulder and hip area could sink too far into the mattress and their spine would be "bowed" the other way.

This is further compounded by the fact that in most people, the shoulder area (for side sleeping) is wider than the hip area but the hip area carries more weight and would have a greater tendency to sink further than the shoulder (more pressure). In this case the shoulder would need to be softer than the hip to help create a flat spine.

So in the case of an adjustable slat base, and depending on the makeup of the mattress and the weight distribution of the person, the slats may be needed to either "firm up" the hip area (if it was sinking too far) or soften it up (if it was not sinking enough). The adjustment needs to be "relative" to the other areas of the body.

So in a "hard" mattress, the hip area may need to be zoned softer so it can sink in more and in a "soft" mattress the hips may need more support so it sinks in less relative to the shoulders.

This finally all made sense to me once I thought about it relative to creating a straight spine.
