Duvet cover for disabled friend

[Pedestriana]

Not sure where other than housekeeping this may get traffic!
I've a friend who has a number of difficulties with mobility and with balance.

He's often cold and had a heavy tog duvet. However, he really struggles to get the duvet in and out of a conventional cover.
Does anyone know where I can buy a reasonably priced cover that is easy to put on? I've seen some online which have zips on three sides but they're around £50 for a double. I pay half that for a conventional king size!
I'm pretty broke but would like to be able to get one for his upcoming birthday. If anyone knows of a supplier/manufacturer can they please point me in the right direction?

Could you buy a normal one and get alterations place to put zips in?

About £40 here.

How are your sewing skills? You could open the seams on a regular duvet cover and put in zips, velcro, buttons or similar. Actually, you might be able to to do the poppers like some duvets have, which I think you get a device to just punch them onto the fabric, rather than having to sew...

I've recently discovered the for changing a duvet cover, makes it much easier, especially with a big duvet. Might help.

these are cheaper (but haven't used them myself)

My sewing skills are terrible!
Unfortunately the roll method won't help a great deal as he would either fall over halfway through (not good at standing for a long time, can't kneel), and has manual dexterity issues.
Must say I have used the roll method and it's great!

Could he use a top sheet instead?

Sorry, realise I'm rather drip feeding.
He could use a top sheet but won't because of OCD.
He also can't/won't go to shops because of sensory overload (ASD).

I was really hoping that the extra zips/buttons were not going to push the price up so much. I don't work and have a very minimal amount of funds available. We've been friends for a few years and he's supported me through some emotional issues. I'd like to get him something both useful and aesthetically pleasing, but I'm struggling to find anything in my price range.

Perhaps I can spend a bit more in lieu of a Christmas gift!

I don't know sorry, but just wanted to what a lovely friend you are.

wanted to say ^

What about having two or three comforters/duvets and using them without covers; with a couple of spares they could be washed and rotated as frequently as a duvet cover is washed?

He doesn't like the feel of a top sheet? or the look or...?

Top sheets have been described as "too oily", "too scratchy" and "too noisy". I think we established that brushed cotton was okay and that some of the ones from IKEA (not the "oily" ones) were alright.

We've known each other for about 6 years. DH helps him out with practical jobs as and when he can as he doesn't get on with his family (youngest of a large brood and ASD was undiagnosed until 5 years ago).

I'll check out the other suggested options but may run the duvet without cover thing past him.
