Okay... this mattress... is a trap lol. I feel sleep come on as soon as I slip into bed, I love this mattress so much. I love a firm mattress but I was nervous to try gel memory because I am so used to spring mattresses and I didn't want to sink into my bed... the gel is great, because it is firm you don't sink deep into the mattress. This mattress is amazing. It was delivered one day before the delivery date. The mattress is rolled up into a box but it expands immediately when you cut the plastic from around it. I love love love my new mattress. My back feels great and I get good sleep. I have used the mattress for about 4 days now. It's worth it.
