TOPIC:

So the thing that isn't supposed to happen, apparently does happen. I just took delivery of my brand new, all latex Savvy Rest queen size mattress last week. I noticed a couple days later a bump in the middle where the split layers meet. I figured the delivery guys did not align completely correctly. So this weekend I adjusted both middle and top split layers (the bottom layer is one piece) and ensured complete alignment. Everything was perfectly aligned and flat. Next morning... bump is beginning to form again - same spot. (Bottom layer - all one piece firm dunlop, middle layer split - med dunlop both sides, top layer - split - med talalay both sides)

I think the issue is I am sleeping almost, but not quite, in the middle of the bed, so I think I'm sleeping right on the edge of one of the layers. I'm guessing that layer now is a bit lower and the other is a bit higher. Given the mattress is only a few days old, I know it isn't an impression already. It has to be some sort of shifting or pushing I'm guessing? Any ideas?

The mattress casing is pretty snug / tight. One of the the middle layers of dunlop was almost 2 inches longer than all the rest - which is the one under the side that seems to be on the "lower" side of the bump where the two top layers meet. According to their site "If a layer appears longer than the layer below it, this is normal. This is not a cutting or sizing error; the latex has simply stretched during transport. "

I'm thinking I should have gotten all 3 layers in one piece instead of going with the split layers. I chose split layers, after talking with Savvy Rest, thinking of future configurability ease.

They do have a comfort layer exchange policy within the first 90 days. I'm happy with the comfort, just not the bump. Is this some sort of defect or a side effect of the split construction - which no one else seems to have but me?! (At least I can't find any other mention of this problem in my searching)

Hi photocat,

Regarding a “bump” in the middle of a split latex mattress, that would be odd (as you surmised), as all the layers would be the same thickness (or have a very slight difference). To help try to determine where this might be coming from, I’d first start with the type of foundation you’re using and make sure that it is not contributing to the sensation you’re feeling. You can place the mattress upon the floor as a reference if you have the room.

The next thing I would do is start from the beginning and remove all of the layers, making sure that your mattress encasement is flat underneath. Then place the first layer in, putting a few “waves” through it to make sure that it is not overly stretched or compressed in one area. While it sounds simple, Do the same with the second and third layer, and make sure when putting the “waves” through each piece that it lines up both length and width-wise, and that where it meets in the center it is not bunched too tightly, as latex is grippy and has a high coefficient of friction. Also, make sure that each layer Dunlop layer is facing with the same side up (you can tell the difference in the 3” mold pieces of Dunlop that Savvy Rest uses). You can place a sheet over the latex after you have the first two layers together to see if you feel the “bump”, and do the same thing when you have all three layers assembled, and then test it again with the encasement zippered on top, attempting to logically diagnose if you can find the source of your complaint.

There will be some breaking in of the product, mostly the covering, during the first few months, but otherwise the latex won’t change too much during that time. As far as the difference in length is concerned, Savvy Rest cuts all of their pieces at their facility to control dimensions quite tightly, but it is very easy to have a layer 2”-3” longer than the one next to it if it is stretched slightly, which is why it is helpful to put those waves through each layer when getting them aligned.

I’d perform those diagnostics, starting with the foundation and moving up from there, to see if you can wither find the cause of your discomfort, or “fix” it with reassembly. If you still have a problem after that, and after having given the product some time while sleeping upon it, I would phone Savvy Rest directly, as they are quite helpful to their customers (they are a certified B corporation).

Thanks Phoenix! You are saving my sanity

To be super clear, the "bump" is where one piece of latex is now higher than the other.

So the mattress starts off perfectly flat - I go to sleep and in the morning one side of the latex is higher than the other. This raised area ("bump") is about 8 inches or so in length and right where my body / torso lays - not down by my feet or up by my head - all of that is still perfectly flat. The raised area starts off small, you can only feel by rubbing your hand over it - but after a few days becomes visibly noticeable.

Foundation is more than fine - brand new from US Boxsprings (thanks to this site!) and even without that, the new bed is equally designed with hardwood slats less than 3" apart.

But I saw your reply before I went to sleep last night so I did a test. I slept right in the middle on top of the split / bump. Not my preferred location but my results = flat mattress in the morning (minus the slight raise I noticed the night before)

So unlike the first week, the raising "bump" issue did not continue to get worse before I had a chance to go in and fix it. I also don't really feel the bump (or the split) when I'm laying on it. I can tell the side that is "higher" feels a bit more firm than the other side even though both are the same med talalay. It isn't a huge difference and I probably only noticed it because of this issue.

Anyway, I know Savvy will let me do a "comfort" layer exchange for a fee but what I can't figure out is if this is "normal" and I just sleep in the most vulnerable spot (right at the edge of the center split in the center of the bed) And if I do replace the top split layer with a solid layer - would I still have the issue, to a lesser degree, because the middle layers are split too.

I'll run through your suggestions on the weekend and continue to "test" and take some pictures etc. I'm just super bummed spending this kind of money when everything I read everywhere and even in talking to the dealer and Savvy said - no problems with the split. And yet, my only problem so far- the split.

Hi photocat,

Thanks for the update.

From the information you provided I would tend to lean more toward an assembly issue with the latex being “compressed” a bit in one area, but until you have the time this weekend to take the layers apart and reassemble you won’t know for sure.

I would also suggest that you spin the layers from head to foot when you reassemble and see if you get the same result.

I’ll be interested to know of your results.
