Good but loses softness on washing

No, I don't recommend this

Good size, nice colour green, easily fits over quite deep mattress. It was lovely and silky on opening but lost that once washed.

Comfortable sheet

No, I don't recommend this

This sheet does not have feel of cotton because it is slippery, and I found it difficult to fold tidily. It is however comfortable enough in bed.

Fitted Sheet.

Yes, I recommend this

Much prefer this to the usual size of fitted sheet, the extra fabric makes it super easy and securely tucks under the mattress. Lovely cool cotton too.

So smooth!

Yes, I recommend this

I bought these following the purchase of a new mattress which is deeper than the previous one. I'm pleased to say that they fit perfectly and don't move about at all. Making the bed in the morning used to be a pain as the fitted sheets needed untucking and retucking every day. Thankfully, all we do now is smooth the sheets with our hands! The sheets are of excellent quality material, they wash well, fit well, feel comfortable - and were on offer too. A winner all round.

Horrible waste of money

No, I don't recommend this

Terrible. 40 degree wash, looks like a dish cloth even after ironing and rustles when you move in bed

Lovely and cool .

Yes, I recommend this

Well made deep fitted sheet , but I prefer the Egyptian cotton, as the Egyptian cotton ones seem thicker to me. Just a personal choice. Still a great fit and a nice cool feel though.

Good quality and great colour choice

Very pleased with the product and would have given it a 5 but found the sides were a bit loose but of course that may be my mattress! Elasticated all round would be good.

Does what it says on the box. Nice deep overhang. Needs a wash before use as it feels quite plasticky
