Mattress Forum

Here is my background:  Iam 150 lbs and primary side sleeper.  Have 2 + 3 inches of Dunlop med/firm (28-30 ILD) latex toppers from Sleepwarehouse. 

I had been sleeping on the 5 inches total latex on a older mattress with boxsprings for the past week and was working nicely.  Than I received my slatted bed and slept last night with the 5 inches of latex.  I woke up with a sore lower back.  This was a first since sleeping with the slatted bed setup. 

I had planned to added 2-3 more inches of 24 or 28 ILD Talalaya from SLB (have 10% coupon) for a top layer.  Now Iam having second thoughts.

Should I purchase a 2 inch firmer 36 or 40 layer and put in the middle or bottom or do you think it just needs more layers and stick with a 28 ILD top layer?

I feel that it is not bottoming out, however noticed more sinking in the hip area.

thanks
