Cushy support - Mince Pie

Just what I expected but I might need to exchange it. I bought the soft mattress. It feels like foam on a rather firm, supportive mattress. Sounds ideal for a side sleeper, but I'm waking up a bit sore in lower back. Honestly, it could be my medicine dose. I have to do a good trial with better pillows, regular dose of my medicine to be scientific. Arrived a day early. I managed to unpack it on my own. I'm a short woman with back pain and I didn't hurt myself unpacking it. It would be super easy for two people. I'm very happy i can exchange it if i need to.

Great Quality for Price

This mattress is comfy! It's not too firm and not too soft. I love it! I was a little nervous before I bought it because the price is so low. Once I went in the store and tested it out, I knew I was going to get my monies worth. Granted I've only had it for about a week now, even my boyfriend has confirmed it's super comfortale. Get it while it's on sale.
