Hi SleepingOnACloud:
I got a queen mattress last year from a particular company, it was the best mattress I'd ever slept on, we love it so much but it's crowded so we decided to upgrade to a king.
Even if you found the same model with the exact same name, it is common for there to be small changes in the makeup of the product over the course of a year. Foam suppliers could change, which could result in different comforts. In addition, there could be small changes in the ILD, density, compression modulus or hysteresis of foams being used. Even the FR barrier could change, causing the overall comfort to change. I'm not saying this was the case with your mattress. When I have customers visit me and try to find a similar mattress to what they purchased a few years ago, I'll always caution them that even if the specifications are listed as the same by the manufacturer, there will most likely have been some small changes and the item will be as close as I can get to the old model, but not an exact match.
I went to a furniture/mattress store and brought the tag with me, asked them if they could order one in a king, they called the company and after a few minutes of looking they said that they do in fact still manufacture that mattress but that the model number had changed.
As a very general rule of thumb, if the model number has changed, this is usually a sign that the product is somehow different.
We double checked to make sure we would be getting the same model and we ordered it.
Unless you have something in writing on your invoice stating that this is the exact same item that you previously purchased (which technically we know it isn't because the model number has changed), then you might be fighting a bit of an uphill battle here. I obviously wasn't a part of your purchase process, nor was I part of the phone conversation that the salesperson had with someone else regarding attempting to match this mattress, so in such cases getting as much written down on your invoice prior to purchase is always advisable. Just ask Judge Milian from The People's Court.
They original queen was a sleepinc and this new king is a renue performance.
It seems you have mattresses from two different lines made by
Corsicana
.
Biggest issue was sitting and laying on it. Much firmer than the queen. It wasn't firm just because it's new and not broken in. When we got our queen it was extremely soft from the get go, you'd sink into it. Not with this new one.I called them a couple days after and the woman on the phone swore it was the same. I call baloney on that.
With a different model number, a different line, different componentry percentages, and a vastly different comfort, it seems like you have two mattresses that are dissimilar.
Same means same.
The only way to be assured of this would be to know every single layer in you old mattress, and to confirm that any replacement mattress ordered used the exact same componentry. And the only way to confirm this would be to speak directly with the licensee making the product, as they would have those details. Often a mattress company will attempt to find you what they consider the closest equivalent to an old model, and that's what they'll recommend. Your definition of "same" and theirs might not be the same thing.
I'm at a loss about what to do
If the company has some sort of exchange policy, you may wish to investigate that. If not, I would contact the licensee making the product and attempt to find the details of each model you have and then armed with that information you could speak with someone in management at the store where you made the purchase and politely plead your case and see if there is anything they might be able to do for you. That would be my best advice - acquire as much objective information as possible..
Not having been a part of the conversation when attempting to match your old mattress, I can't speak to exactly what was conveyed or understood by both sides - I wish I could offer a more definitive solution. Much of what I'm commenting upon here will serve as more of a cautionary tale for those attempting to "exactly" replicate a mattress that they previously purchased. This quite often can be a bit of "chasing your own tail". Additionally, a current mattress would have undergone one year of softening, so it would certainly feel slightly different from the exact same model that you chose a year ago when new (although I know you stated the feel between the two is significantly different). Attempting to find an exact match can often be a frustrating, if impossible, quest.
Good luck!
