The sheet fits well however it feels very thin and not like I would expect for 300 thread count.

Lovely material

The material feels lovely, but the elastic doesn’t hold the sheet in place so it needs refitting every couple of days.

Terrible Quality

Originally posted on marksandspencer.com (UK)

Awful bedding. Crinkly and cold to the touch. Washed and dried as per instructions, even after a ridiculous amount of time spent ironing, it still looks like creased. Bought this for the guest bedroom but would be ashamed to put it on the bed. I bought a full bed set in the 300 count range, complete waste of money. Will be sticking to the fabulous 230 count in future, which washes like a dream!

Initially i thought it felt like a nice fitted sheet but having only been on the bed 24hrs it had a rip in the middle of the sheet

Perfect for those who change bedding on their own. No more struggling to fit the corners of the sheet over the corners of the mattress. Perfect item and good value, too.

I bought extra deep fitted sheet. They are good quality sand wash well. However, the “extra deep” is a little bit too deep but this is my fault for not checking measurements.

Superking fitted sheet

Originally posted on marksandspencer.com (UK)

Super king size fitted sheet, too large for the mattress, didn’t return as I couldn’t pack it all up again plus I’d washed it before putting on the bed. The material is lovely though, very smooth and the colour matches my existing bedding. I’ve always bought M&S bedding but I’ve never had this problem before.

Not sure about this sheet. It comes up very big and after washing is very creased and feels like paper!
