Love the mattress topper. Very comfortable! I had an Englander mattress set with a memory foam topper built in and I loved it. It lasted about 8 years and the company replaced it because the indintations where deep. I picked out a different mattress, which is very nice but it isn't as comfortable as the last one and I have trouble sleeping anyway. I decided to try a mattress topper. I did a lot of research and looked at reviews. I was trying to find something that didn't hold heat because I have hot flashes. I decided to try this one because of the reviews and it has the gel mixed in to help the airflow to keep it cooler. I really like it and I am sleeping better. I read a couple of reviews that talked about the smell being bad and lasting. I used my topper the night that I received it and didn't smell anything and I have terrible allergies and asthma. I highly recommend this one!
