Where do you find affordable sheets for a sleeper sofa?

[Jacqueline955]

I have a queen sleeper sofa that I am trying to find sheets for.  The mattress dimensions are 72"x60" and the current mattress is 3.5" thick/deep. They sent the wrong mattress, the correct one is coming and it is a memory foam mattress.  I can't imagine the new mattress will be much thicker.  Do you buy sheets specific for a sleeper sofa somewhere or do normal sheets fit?  I don't want the sheets moving around all night because they are too big.

@Jacqueline955 If you don't sew yourself, or know anyone who does, you could take sheets to a seamstress and get her to alter them a bit so they fit snugly- it's a pretty simple alteration. Or use a flat sheet and have it sewn into a well-fitting fitted sheet. Your bed dimensions aren't standard, even discounting the depth, as standard Queen size mattresses are 60" wide by 80" inches long, at least in the US and Canada.

Perhaps there are odd sizes available online, but I've never looked for that.

If you can find Full or Double bed sized sheets (54 X 75) that do not have defined corners sewn in and full elastic around the bottom edge, you will have plenty of sheet under and around the larger but thinner mattress.  Most sheets nowadays are made for mattresses that are as deep as 18 inches, which adds a lot of material.   I cannot tell you what linen makers sell these type of sheets, but most of what I have found constructed without corners and full bottom elastic are microfiber, not cotton. 

 @Sarah977  has a very good suggestion for altering flat sheets too.  If you are in a pinch, I would just make up the bed with two flat sheets.
