Bought for a student house. It seems ok, not quite as nice quality as I expected for the price, but I daresay it will do the job.

Super quality and fit and although it’s waterproof there’s no crackling when you move in bed and it’s very comfortable to sleep on. Great price and would highly recommend.

A good quality waterproof sheet that has enough tuck in as have a topper over a mattress. Like the quilting which gives the top sheet a soft feeling.

Good choice

Originally posted on marksandspencer.com (UK)

Well made quality product. Soft quilted top, elasticated skirt, fits a deep mattress perfectly. Very lightweight. Waterproof lined but doesn’t ‘rustle’ and isn’t hot to sleep on. Haven’t tested waterproof-ness, hope I never have to!
