Have had trouble with other mattress protectors not fitting our deep mattress without slipping off at corners but this fits great and so doesn’t move

Our other matress protector had seen better days so I was looking for a soft (not crinkly) one before it started getting cold. Fed up of fighting to get them on and stay on, I picked this deep one. Tried it out and its nice and comfy and easy to get on. Probably buy another so I can swap over for washing.

Bought as a replacement and we're very pleased with this mattress protector. It's great quality, doesn't move or slip like the old one and is ideal for purpose. Would recommend.

Excellent mattress protector. Nicely padded & quilted top and absolutely famous skirt to fit onto the bed. Really long to tuck under the mattress, after a week it had not moved !!

It is a great fit for our new posture-elevate mattress. It stays in place and that means a lot, because both my husband and I are restless sleepers.

I brought this mattress cover for my personal use. I find it so soft and comfortable. The fact that it fits the depth of my mattress is also a feature that I like. It washes well too.

Perfect depth with enough fabric to allow for the elasticated skirt to tuck under the mattress so it doesn’t wriggle free. Good quality and thickness, well worth the price
