Cotton bedding- big ask ?

[schoolcook]

Hi I'm getting increasingly frustrated trying to buy bedding and I wonder if anyone can point me in the right direction ?

I'm looking for a double fitted sheet ,100% cotton with a depth of 28-30cm. Colour a deep purple - plum or aubergine are the usual suspects.

Also to go with it a single duvet set , 100% cotton , same colour / colour scheme as the sheet. Don't mind patterned or plain.

I am getting extra deep sheets with a 25 cm depth or described as 100% cotton then it's 50/50

I'm not sure where I'm going wrong - usually just nip up Asda and grab whatever is on offer so this is new to me

Dunelm

Wilco and B&M both have cotton purple sheets and duvet covers

Thanks again I got distracted so am no further on

I will try all your suggestions over the next couple of days.

Oh and having measured my mattress it's actually 25cm so that should make it easier.

Brand Alley can be good

Next are really good too I have the brushed cotton

You will probably get the best deal on amazon.

I'd also try and get a cooling mattress protector.
