C’mon, Woot! I have a split king (Twin XL). You never offer Twin XL. You always have every other size except that one.
Any way to figure out what brand this is so I can find some reviews?
Future Foam
I bought the firm full version of this last spring and love it. If you’re wondering how to know which version to get, there are guides on the interwebs with recommendations.
It comes compressed and rolled up. Be warned: as soon as you start to cut open the plastic, it will start to decompress rapidly. Be sure to have room for it to spread out. It will be ready to sleep on that night.
When I go to future foam website it just brings up different brands sold on different sites. Guess I’m struggling to try and figure out the actual brand like Zinus, Purple, Tempurpedic, etc. Obviously it’s none of those.
The brand is Future Foam. (Edit: I know it’s weird.)
If you want reviews just search the forums for “luxury gel 12” and you’ll see a bunch of threads where these have been sold before. Click into those and check out the reviews.
This company makes mattresses for the brands you mentioned. This particular mattress isn’t a huge brand, which makes it cheaper, but it’s the same manufacturer. There’s no name brand surcharge, in other words.
(Please note: I don’t work for Woot, I just volunteer to help out here on the forums.)
Need to replaced my mattress bad, but will the memory foam mattress remember me?
I bought this mattress (Medium Queen) on Woot about 7 or 8 years ago. It’s been great - I still sleep on it and it feels the same as a TemperPedic. Here contemplating if I want another one for my guest bedroom… 
And my obligatory copy/paste from previous sales:
Since EVERY time this mattress comes up the exact same questions are asked, lemme save some of you the search:
and
for starters.
We bought this September 2020 (king, firm) and we love it.
