At a comfort scale rating of 1.5 out of 10 (10 is the softest) the limited edition has an exceptionally firm, dense, comfort level. If you're looking for one of the firmest mattresses available, this is it.

The power packed coil system uses individually wrapped coils that contour to your body's unique shape better than traditional tied units, while promoting proper spinal allignment for outstanding support. It's great for light sleepers because it reduces motion transfer when movement occurs, and it's adjustable base friendly!

The Luxury Cotton Fiber Quilt feels soft to the touch and conforms well, allowing the comfort padding layers to perform.

High Density Gel Memory Foam offers superior pressure relief to help reduce tossing and turning, outstanding durability, and helps reduce motion transfer for undisturbed sleep.

All Ashley Sleep foams are independently tested and certified to meet or exceed the higest quality standards.

If you love an extra firm comfort level and want to keep your cost relatively low, then the Ashley Sierra Sleep Limited Edition Firm checks all the boxes. Another nice benefit is it ships conveniently via UPS or FedEx, in a box about the size of a golf bag, which means an extremely easy delivery process.
