Mattress Cover Product Suggestions

I have a diy build:
6" blended talalay core (split king), 3" medium talalay king, and 3" soft talalay king. For 12" total

I originally ordered a mattress cover same place I ordered the core and was sent one too small (72 x 76) so I had to send it back. As a same day solution I got a zip off top mattress encasement but it made it too firm.

It was much softer without the encasement so I ordered a Wyoming king encasement to ensure it wouldn’t fit too tight or make it too firm
Turned out to be an absolute pain to put the layers in because it only zips around halfway in the middle rather than being zip off top or 360. The layers have already shifted. Plus it’s terry cloth and I dislike the texture

I started looking at mattress covers again but my partner insisted we measure all the layers before buying because the two toppers look slightly bigger than the core pieces. Turns out both toppers are slightly bigger than a traditional King size at 78" x 81.5" - 82" so I’m worried no matter what mattress cover I order, I’ll end up with the ‘too tight making it too firm’ issue all over again. I absolutely don’t want to try cutting the latex to even it out, feels like it’d be butchered that way.

A reddit post suggested sleeponlatex said their topper cover went up to 12" and wasn’t as snug, easy returns. I don’t want to keep ordering things that aren’t gonna work though

Any product suggestions for a King mattress cover (when the latex is slightly oversized)?

Hi Kea12312.

In this case, you may wish to consider something a little larger than you actually need, but not TOO large so as to not run into the issue you had with the Wyoming king. These options from @TheCleanBedroom may be worth looking at!

I’ve tagged them here, too, so they can provide any insights they may have.

Thanks, Nikki, for the tag. I concur with Nikki that you may want to try a little larger. 78" x 81.5" is a little bit bigger than either of those encasements, though, so I worry that it will again give you that firm fitting. Of the two, the Sleep and Beyond is more stretchy - but not exceedingly so. Perhaps a 14" thick encasement would be a less tight fit.

That said, both of those encasements are made as mattress protectors and not mattress casings, so I also worry that they would not be as durable as you probably need.

Edited to add - you are able to order encasements from us, and if you call us, one of our staff can help you find what you need. I know that Obasan, Naturepedic, and Healthy Choice all have encasements and you could see if they fit what you need. They can also do custom encasements.

Hope that helps a little and that you find what you need!
