Got it for my daughter’s bed – would fit a deeper mattress too.
Easier to get on than I expected – is zipped right round.
Feels good quality – not too crinkly noise, but not silent.
Will protect the mattress against any accident spills or leaks.
Would recommend

Decent quality for the price.

This is a good idea if you have a rental property so that you know your mattress if fresh. It is a bit fiddly to get in but when you have it is fine. I use under a mattress topper so I can’t feel it at all. Useful product
Mr J L Chiswell –
Terrible quality. Zips broke immediately
Michelle Ann Nangle –
This is an excellent waterproof cover as it covers the whole mattress which is hard to find. Perfect for kids beds to protect against spills etc!

A great mattress protector from Silent Night, easy to fit and generously deep. I’ve been able to cover my son’s mattress and mattress topper at the same time due to the depth. The fabric has a lovely soft feel to it on the outer side and a waterproof backing on the inside. I wouldn’t say it’s 100% quiet, however it makes more of a familiar fabric sound, certainly not a harsh crackle or anything loud or disturbing. I ordered this more for anti-allergy dust mite protection, however the waterproofing is also reassuring. I’m not sure I’d want to change a full mattress cover in the middle of the night if someone had an accident, but as an added layer of protection it’s a definite bonus, and it can be washed at 40 degrees.
The cover feels very good quality and as though it will last well – I’m very pleased with it indeed; hopefully it will also prolong the life of the mattress and keep it looking fresher. This would of course be an added bonus to anyone using a pre-used mattress, such as a student or lodger, and certainly works to freshen up the mattress’ appearance too.
