Mattress Forum

My new pocket coil w/2"latex is pretty good in the sense that it's not hammocking, but it's still way too firm for my side sleeping.  Shoulder and arm really hurts all night. 

Anyone know of an inexpensive mattress topper (I think I should go with memory foam to allow shoulder and arm to sink in)?

It would be best if I could buy it in-store but if there's a really good one on-line I'll try it.  I'm 125 lbs so would you take that into consideration regarding density and thickness?

Thanks
