Check before it’s sent out

The product is exactly what I needed but it arrived with loads of marks. Looked like it had been plastered with stickers or something. I didn’t have time to return and order another. Luckily it washed out after pre-treating.

Beautiful quality!

Yes, I recommend this

I really love the smooth silky texture and cotton comfort of these sheets. The flat sheet is beautiful and the deep fitted sheet fits my mattress perfectly. This is the 2nd set that I have bought, and I have tried many sheets over the years.

Sateen is cool and smooth

Yes, I recommend this

Lovely cool feel to the sheet but thinner feel than expected. Sateen was purchased in error, will return to usual in future.

Not the quality I expected

No, I don't recommend this

Sadly the sheet (which was for a king size bed and ordered appropriately) touched the floor on either side - way too big for a king bed. The sheet, once washed and dried is ok but for 400 thread count I would expect it to feel thicker. I won’t order again from M&S

Excellent quality

Yes, I recommend this

These sheets are excellent quality, they are lovely and soft on the skin. I personally like a crisp white sheet, these fit the bill whilst having a really super satin feel

These are beautiful quality, I have them in another colour and they don’t fray or look worn at all, definitely worth the extra money, they also feel very soft.

High quality linen

Yes, I recommend this

Lovely linen from M&S. Very pleased with the sheets I bought. M&S has really good sheets and are my go to when looking for linen. Good choice, washes and irons really well and comfortable to sleep in.

Not to my taste sadly

No, I don't recommend this

I was disappointed by the sheets - they were quite an odd feeling and snagged when I washed them before I even got to use them. I did return them

Good quality flat sheet

Yes, I recommend this

I have had problems finding good quality flat sheets and this one is really nice however I do not understand why it is on-line only and therefore have to pay for delivery why is it not possible to click and collect?

Disappointing

No, I don't recommend this

I’m disappointed in these sheets. I bought the same 400 count double sheets a couple of years ago and they are far better. The double ones are very crisp but the single ones aren’t the same. I wouldn’t buy them again

Great colour

Yes, I recommend this

Not quite the colour on line but a richer more intense blue and all the better for it. Love the silky feel of sateen and great value too.

Bit disappointing

No, I don't recommend this

The price was good especially with the offer at the time of purchase. However although adequate the fabric felt rather thin and demonstrated how a 400 thread count description does not guarantee quality Certainly compared with a similar 400 count sheet (more expensive) woven in Portugal this product showed clearly that you get what you pay for.
