I purchased a mattress from a local mattress manufacturer who is a member of, and highly recommended on this site,
We went with a flippable matteress - 2.5" dunlop latex (medium firmness) on each side, and pocketed coils (quantum?) as the middle. The latex layers were sewn in to act as a “pillow top” (not that we preferred that, but they said it was the norm).
We received the mattress a week and a half ago. The first night was AMAZING. However, after 5 nights the latex had sunken in roughly 1.5" in the areas that my wife and I sleep. We proceeded to rotate the mattress, and that side ALSO sunk in to roughly 1.5" after the first night.
We called the manufacturer, who suggested to flip the mattress to see if just the one side of latex had a defect. We measured the indent right after flipping, but before sleeping - there was virtually none. We woke up this morning, measured, and found a new indent of roughly 1.25"! Now, my wife and I are not heavy people. I am 170 lbs, and my wife is about 120 lbs. The manufacturer came out today to take a look at what was going on. They inspected the bed frame (king), and found that there was adequate support underneath the bed (extra leg?), and that the box springs were also in good shape.
After checking it out, the manufacturer agreed that this was not normal, and said they would let us pick a new mattress. I was happy to hear this, but they added that we probably shouldn’t use a medium density latex + pocketed coils, because “it might be too soft for us”. Now, we like a medium-soft bed, so I was surprised to hear this. Soft is one thing, but 1.5" impressions after just a few nights does NOT seem a case of it being “too soft”. It seems that there could be a manufacturing defect in the latex and/or coils?
Should we do a different two-sided combination (we WANT two sided/flippable - one of the main benefits of working with a local company), or should we suggest to the manufacturer that they use a different batch of latex/coils? Or maybe ask them not to sew in as a “pillow top” style?
We really like the fact that it would be two-sided, we really liked the feel of the coils and we also like the benefits of the latex, but we DO NOT want to have this new mattress sag so much again so quickly. We don’t want to have them create a new one, only for this to happen again. Is a two-sided latex + pocketed coils always going to sag this much?
Any suggestions? Should we have them make the same thing again (and hope the batch of latex/coils is not the same? Or go with firmer latex on top and keep pocketed coils? Or go with foam on top and keep pocketed coils?? Go with latex and foam base instead of coils? Etc.
Really at a loss here. Any insight would be greatly appreciated…
