I have just got assured firm zzz atrlier mattress but the thickness of mattress is just 20cm which is very low compare to my old mattress of 36cm.
Firmness is good for my partner and I am also adjusting to it.
But I want to add mattress topper of 8cm to increase the height and also the gap under headrest i see because of low height of mattress.
any suggestions for thick mattress topper that will keep the firmness?
