When I was dusting and cleaning in the living room I realised that although we have six chairs in our dining suite only two of them are used regularly. In fact there are four at the table.
The table extends to an oval and then seats six people when required.
One of the extra chairs is used in my sewing room.
The other is in the corner of the dining area.
I have decided that in order to keep them all in good condition I will rotate the chairs at intervals of six months. This will ensure that there is not one in the corner which consistently exposed to the sun and also that the same two do not get constant wear and tear whereas the others are rarely used.
Do you have things that you rotate so that they all wear evenly?
I also rotate the bedsheets (3 sets), bath towels (4 sets) and teatowels. I always take from the top of the pile and replace the freshly washed ones on the bottom.

Chairs are definitely a problem for us. We also have six, and since there are rarely more than two of us at home we have four chairs that never get used. Even with using one as a desk chair, they just take up space most of the time!
We don’t rotate them, though maybe we should. The table set is 30+ years old. We figure after that many years of family dinners, our two rear ends won’t do much damage.
I agree that sitting on them won’t do much damage. My main concern is the sunlight on certain areas as we do not have any curtains.
I have decided that next time we turn the mattress I am going to rotate it as well so it gets more even wear.
I have always rotated linen and towels.
We rotate and turn the mattress from time to time – about every 3-6 months I suppose.
I wash all my living room and dining room curtains together then re-hang them. I’m sure they get mixed up a bit over the years. Maybe I should be more strategic!
That is one thing I don’t have to worry about – we do not have any curtains.
For me I think mini-blinds are sooo hard to clean so I’m glad I have mostly curtains. We don’t have fancy ones though so I just throw them in the washer and hang to dry.
