On the whole, the mattress is good for the price. Not too Firm and nice built- in topper adds to the comfort. Slightly disappointed with the side / edge build quality as rather thin and the springs push on the thin material making it feel lumpy and cheap. Sort of feels like the springs will quickly wear through the edges, but time will tell. 
Dropped a star because the courier used by Wayfair (Panther) were truly awful. Had message after message indicating various conflicting delivery times, a missed delivery day and then on final delivery day completely messed up delivery slot . Total waste of time and completely unnecessary considering how good some couriers are at sticking to a 2 hour delivery time. Also the mattress had been folded in half despite instruction on the packaging saying not to.
