This is an amazing mattress for the price. On a plush scale from 1-10 it’s a 6.5 
A great balance of firm and soft 

But do your homework, go to the store and try it out before you buy. Also search on YouTube, there 5 or 6 different types of this silver edition. From coil count (which the 900 stands for) to the letter C edition, which stands for cooling technology 

Wayfair by far has the best price on this 
Paid 725.04 with delivery and old mattress take away. But make sure you show the delivery people the order receipt for take away. They will try to say they don’t have room in truck or you didn’t pay for it. 
But it’s included when buying from wayfair 

One last thing is it does take a long time to deliver 2-3 weeks 

Hope this helps
