Hi FreakingCapacitors, Welcome to the MattressUnderGround!
Despite not being a Trusted Member here, I think helix makes a nice mattress. Some folks are successful having purchased their product and others not as much. It happens. I am a Brooklyn Bedding Owner myself, before I came to TMU. Would things be different now. Who knows.
In your case, you have a BMI about what mine was when I bought my BB Plank Luxe. I was 250, now I am 200 and BMI down to 28. Of course, your distribution of weight is a bit different than mine, but be that as it may, you may have been better served with the Helix Twilight, a slightly firmer version to the Midnight, still able and designed to accommodate side sleepers.
The Helix Midnight based on my last chat with Helix is
Helix Midnight Core Mattress

First Layer: Flame Retardant Layer - FR Fiber Quilted to Cover Material Foam Layer - 1.5 inches

Coil Unit - 8 inches Standard, Side Edge Support (reinforced edges)
Base Foam Layer- .13 inchesDuraDense Foam, 36 ILD
Approximately 11.5 inches total
The mattress gets progressively firmer as you approach the support layer, but is very soft in the upper comfort layers. This is an issue.
Considering your circumstances, I would try a couple of things. $300 to return a $1000 mattress in my estimation is not a good trade. Everyone’s financial situation is different, so keep in mind, this is coming from a place of, how you can rectify your problem, not finances. I will leave that part up to you.
First thing is I would call helix and ask them to send you a Free Topper, the firmest one they have to offer. I know BB will do this at the sister division. I am not sure how close you are to the end of your trial, hopefully, you have not exceeded that yet since you mentioned there is the option to return it at a costly amount.
I would consider looking into the BB Microcoil Topper or their Firmest Talalay Topper, it is a 3" 36ILD. The 36 ILD in the talalay sounds firm, but at 3 inches will offer a bit more plushness and support at the same time. The MC is close to 4" and will have a different type of feel. It will become a matter of floating on top of the mattress feel vs a little bit of sinking feel with the MC.
Remember, toppers do not normally make a mattress firmer. It may add a bit more support, contouring for the curves, and pressure relief if needed.
One more observation. A pocketed spring mattress is designed to be slept on, and support the full length of your body, contouring and allowing your entire body weight to be distributed accordingly. When sitting on a pocketed spring mattress, your body’s entire weight is concentrated through the “bottom” area, which a smaller area of pocketed springs is attempting to support the same entire body weight equal to that when you are lying prone on the mattress.
When “sitting” on the mattress like a chair, this will cause considerably more compression to the limited number of springs attempting to support your entire body. This is not an indication of weak springs, or poor edge support. Good or bad, it is just a fact of physics.
If the topper does not work (a free one that they may send you, or one you need to purchase as I described), and you are still within the trial period, you are already one layer into a DIY mattress, if you have to go that route.
What are your thoughts?
