Hi TheDon,
Thanks for taking the time to share your feedback … I appreciate it.
It sounds like your mattress may be too firm for you (which wouldn’t be that surprising with a firmer mattress for a lighter side sleeper) but the good news is that you had the foresight to buy a mattress with a great return policy which gave you the chance to test the mattress at home with very little risk.
It may be a good idea to wait for another week or so to give the mattress a little more time to break in and for you to adjust to a new sleeping surface (see post #3 here) but if it is still too firm then you could either purchase a softer topper to add some additional softness and pressure relief or return the mattress for a refund and choose a mattress that is a better “match” for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences).
