This listing is for 3ft 6" (42") wide x 6'6" (78") Fitted Sheet that is A 10" box for upto 9" mattress, it has been designed, Cut, Sewn and packed by us to fit your mattress perfectly. The secured elasticated boarder makes it very easy to slip on and off your mattress when washing is required. If the size you require is not listed, please contact us and we can make what ever size you require. The 200 Thread count Polycotton is great at recovering its shape after washing and drying and sits firmly in place no matter how much wriggling you do throughout the night thanks to its strong and secure elasticated corner. The material you buy is a variation of picks and thread counts, the thread count and pick is the amount of threads per square inch so the more threads the better the quality. We only run 68 pick material and 200 TC (Thread Count) which gives a really nice hotel quality feel. Please be careful of other sellers selling a cheaper 56 pick 144TC which will fade and bobble very quickly in the wash, this sheet is also made up of 50% natural cotton and 50% polyester which helps to keep the material from creasing and gives a much longer use. How to wash & dry your Sheet To get the best out of your sheet and to ensure you get the years of use, here's just a little bit of info to help you wash and dry your product. Firstly a machine wash would be best on a 30 -40 degrees centigrade temperature 5-10, please allow to cool down a while before tumble drying. Tumble drying would also be best on a low heat to avoid any shrinkage and can be taken out while still slightly damp and folded without the need to iron, If you prefer a pristine appearance then minimum ironing may be required. Please do not wash with darker colours with lighter colours Delivery All our products are sent out the same or following day as standard via yodel48 delivery but please allow 3 - 5 working days in busy periods.
