After researching for a couple of weeks, comparing brands, thicknesses and content, especially relying on customer reviews, I decided to try the Grande Hotel Collection 4-inch MF Topper. I made the right choice! I needed something-could not afford a complete memory foam mattress set and decided to try a topper. I've been using the egg crate side and what a difference! I'm sleeping better, no back aches when I wake up and I'm sleeping with fewer 'wake ups' during the night. Highly recommend this mattress topper if you can't afford a complete mattress.
