Mattress buying advice.... Northern VA

Hi!

My husband and I are looking to buy a mattress. We live in Northern Va. I am a side sleeper and am 5 3" and weigh 170 and my husband is a side/back sleeper and he weighs around 175.

We both generally like firm mattresses. What would be the best mattress for us memory foam or latex. Currently we have a mattress from IKEA which is a combination of latex and foam. We like it but wanted to see if there was a better mattress out there for us.

Any ideas/suggestions are appreciated! Thanks in advance.
