Priage by ZINUS 8 Inch Quilted Pocket Spring Mattress

It's been yeeeaaars since I got them, so those exact products aren't available anymore, but any 2-3" memory foam topper should do fine, and the fiberbed topper was basically [just like this one](https://www.target.com/p/ultra-loft-down-alternative-mattress-pad-casaluna/-/A-82038535). As for the mattress, you're looking for a firm pocket-coil innerspring (not a Bonnell coil) without any pillowtop or "hybrid" foam layers, and preferably double-sided/flippable -- e.g., [something like this](https://www.bedbathandbeyond.com/Home-Garden/Priage-by-Zinus-Select-Tight-Top-8-inch-Queen-size-Spring-Foam-Mattress/6756791/product.html) (not clear if that one's flippable tho').

I have a 7 year old Zinus 12 inch and it's still great. I just got 8 inch, I think, for my kids beds. Theirs are super comfy as well but it's only been a couple of months so I'm unsure about longevity.
