So as part of damage control (having bought a mattress without help checking for spinal alignment and only being able to do a confort exchange) I am about to obtain a rock bottom cheap mattress with vertical coils, which is likely the same as this as it’s by the same manufacturer at about the same price point, though it’s 7". The vertical coils seem to be similar to pocket coils, except they don’t have the individual encasement. According to my research it’s got 460 VertiCoil Innerspring; 13.75 Gauge Steel and a foam encasement.
I already have a 2" latex medium topper from SOL, and I was thinking of buying 2" of memory foam from probably foam by mail, in either the 4 or 5 density (probably the 5). I figure the foam in the mattress will probably fail, but it won’t be much and when that happens I can just cut it open and pull the foam out and keep the springs, which even in a cheap mattress like this shouldn’t fail on me.
About how I sleep: I sleep with my partner. I am a side sleeper, 5"7’ 180 lbs with some back issues that the mattress I chose doesn’t work for. I’m a bit of a snowflake, but after testing beds I’ve learned I like latex and I like hybrids with memory foam. Medium beds have been the best for me, and I don’t really like sinking into my bed much. I really enjoyed the serta Stay.
My partner is 230 lbs, 5"1’, so close to the threshold of having durability issues. He sleeps on his back and side, and so far is blessed with being extremely versatile; no bed we’ve tried hasn’t worked for him, though he sleeps hot.
I’m worried about the latex being too firm as the top comfort layer (I’ve only ever tried it on firm beds though), but I’m also not sure about the memory foam being on top because I would probably have to get the 5lb type, which looks like it might have the “sinking” feeling I dislike. The 4 lb looked more suited to what I want, but with my partner’s weight, I’m not sure how well it would hold up.
Anyway, tldr:
Getting a very very cheap firm vertical coil mattress, 2" 5 lb memory foam, 2" medium latex: bad idea or worth a shot? How likely is it that the top two layers will end up being so soft it hurts my back? Or is there not enough transition stuff? And can you substitute a mattress that’s got pretty much just coils instead of using a coil setup from arizona premium? It seems like the coils aren’t usually the weakest point, but maybe I’m being dumb.
My alternative is to just count the money spent on the spring mattress as a total loss and go to a mattress store locally, as I live in DFW where I have two good options, though if the sales person gets it wrong I’m just stuck with something I might hate, as opposed to being able to add some extra layers to my setup. I am very much a diy type in general, so I don’t mind if I end up needing more than just the two layers I was planning on.
