Very happy with this product.
Having purchased and 'road tested' King, Double and Single sizes for this I can report well on all . . .
I am obviously an 'aggressive sleeper' as I used to destroy mattress protectors within a couple of months.
The fitted corners always seemed to rip leaving me with the discomfort and irritation of sleeping on ridges!
Perhaps previous brands have skimped on material leaving too much stress on a standard mattress fit at this size?
Have had a couple of these ones for 6 months now and they are still going strong with no suggestion of impending destruction!
They are not a super cushioned, air pocket type that will transform a hard mattress to a soft one, they are essentially unnoticeable - which is what I want. My mattress provides the comfort and this is designed to stop that getting ruined from a coffee spill say. They are certainly thick enough to protect on this front.
Thick, fitting well, staying put and not under stress - perfect.
