Hassleless mattress

My partner and I went to a local mattress store that doesn't have any employees in the showroom. We are moving soon so our plan was to try out some mattresses, find something we like, then shop around different places to find the best deal. We found one we both liked but the problem is it seems that the model's name might be exclusive to that store. Is anyone here able to help identify what a more universal name for this mattress is? Link to the store's listing below:

Sealy Jasper Plains A Mattress ~ Geneva Ruby Plush Tight Top - HassleLess Mattress

Hey all, I just went into a store and tried a mattress that we really liked but found, what I believe to be, the same model online for a better price. I think the Hassleless one is just a custom name for them. Only difference I can seem to find is the 2" Medium Comfort Foam on the Empress vs 2" Firm Comfort Foam on the Rainier. Do you think these are basically the same?

Hello! My husband and I went to a HassleLess Mattress to flop around on the mattresses. It was a joy to not get dogged by someone while seeing which mattress was the best candidate for a nap in public, in case anyone else wants to/needs to go out and try to get a feel for what they need in their mattress search.
We settled on Beautyrest Rainier Terrace A as our favorite of what was there. Here's my concern, it's a lotta bucks made by an 'S' brand company :( I've lurked long enough to learn they are problematic and are open to similar feels in other brands or a DIY. If this particular Beautyrest is alright, woo, we'll jump on ordering it, but I don't want to toss about $1400 down the drain if it's terrible construction/materials.
The Essentials:
Humanoid 1: 5'3" 185lbs and shrinking - 90% side sleeper, 10% back
Humanoid 2: 5"11" 235lbs and shrinking - 70ish side sleeper, 30ish back - is a furnace
Queen Size bed
Budget: $1500ish, we have wiggle room if need
Helpful Information:
I would like the new mattress to last a good long time, something in the 6 or 7+ maybe(I don't know if this is realistic or not)
Current mattress: Amazon Red Nomad 10" memory foam, it was like $300 and we were desperate for a change at that time(November 2016)
Before that was a BedinaBox, that we wrung about 8 years out of.
Preferences: We're not committed to memory foam or any other product. Young(ish) and dumb and thought it would be a better option for Humanoid 2's morning back pain(lower back). Humanoid 1 has been developing morning back pain as well(lower back) and reading this forum leans to firmer will help correct this.
We are planning to order the Beautyrest Black Luxury adjustable base. Zero G position was heavenly for both of us in both back and side positions. H2 has life long allergies to everything in the air and we're hoping that having better head elevation will help keep gunk from pooling in his head as well. It's smart home enabled, and H2 is hoping to link it in with the rest of the smart home things so the bed can give us it's closest equivalent to the George Jetson treatment in the morning if necessary(we are both very heavy sleepers, 2 timed lights and 4 alarms sometimes can't get us up). I'm hoping getting better quality sleep will also help us get up in the morning.
Google album with name, and mattress construction picture. I can add the QR code for HassleLess, and pricing structure if it would be useful. I don't want to be an ad, but I do want this long post to be as thorough as possible https://photos.app.goo.gl/mo4GTgRDExmArNtr8
Thank you so much for any advice you can offer. We really appreciate how much everyone here tries to help other users.

My Fiance are just finishing remodeling our master bedroom, and at this point we've had our current mattress about 10-12 years now and really need a new one. Unfortunately, we really don't know where to start looking. We have plenty of options near us (mattress firm, Steinhafels, Macy's, Hassleless, Ikea, Bob's Discount, etc), but could use a suggestion on a few bed options to start with to try out considering our needs.
We are looking for a queen or california queen mattress, a king is just a bit too wide to fit in the area of the room (dormer) that we are looking for. Both of us are combo sleepers and my fiance is about the equivalent of a blast furnace when she sleeps and I'm not too much better so something on the cooler side would be preferable. I'm also a fairly active sleeper and toss and turn frequently, however force transfer isn't a huge deal as my fiance is a deep sleeper and has slept through a fire alarm before.
Currently our mattress is a medium-firm (not sure of a rating) and we have a fairly plush topper, so something on the medium-plush side may be good.
Both of use kind of despise memory foam (active/combo sleepers and we both sleep hot), but it is possible that we have only had the experience of poor quality memory foam mattresses in the past.
Does anyone have suggestions for a few mattress options to try out that may fit our needs?
