Enjoying Euro Foam Top - Good Bargain Mattress Overall!

I am really enjoying the Euro foam top and edging - I've had mattress almost two months. Ordering online, I am happy I chose the Euro 9 over plain or pillow-top options. The Euro foam cover gives nice feed-back and finishing. As foam mattress get smushy and cave-in faster then coil I am glad I opted for this firmer-type of foam mattress. It is not too firm, and I am noting some sinking in the middle but ok for the price as the ‘layered’ foam support overall is good as I use this full size mattress. I am thinking I will need to rotate mattress within the next six months, and I doubt I will get the life (fifth-teen+ years former coil mattress). Glad I purchased this NON-boxed-rolled mattress option arriving flat and ready to use. I miss the firmer side-support you have with traditional steel coil, but like the over-all response and hug of this foam mattress (especially as I am a side sleeper). I would not recommend if you are over 250 pounds or sharing bed. I placed my Calm 9 Euro Top onto a traditional average height box frame used with previous spring mattress. So height is lacking. I purchased a full mattress size, but in reality the Sleepy's Calm ends up (I measure with a tape measurer) being about 8.5 inches tall (not nine inches high) and about an inch and a half narrower than a traditional full. It seems all foam mattresses shave off inches. Others report that the mattress does not stay in place upon the foundations they are using. I have had no problem. For the price (was able to apply two coupons) I am happy with my purchase.
