Take old/previous furniture to the new house or get "everything" new?

Does anyone also take old/previous furniture with them or is almost everything replaced?

We took our bed, an armchair, a table, a few cellar shelves and a nice worktop for the laundry room in the entrance area, and a sofa for the entrance area, 2 display cabinets which now stand on the covered terrace, a small apothecary cabinet, a garden table with 2 benches, and the artwork. We gave away the dining table and chairs. We left the kitchen and cabinets for the buyers in the house, the living room sofa was old and of no special quality. We newly acquired a kitchen, a chaise longue, 2 mini desks, a sideboard, a bookshelf, a wardrobe, a sofa, dining table and chairs, 3 stools with trays as side tables for the sofa and next to the bed, cabinets for the entrance area, and various garden furniture for the terraces. The children took the desks with them and each got a new bed, a wardrobe, and a kitchen. We wanted a fresh start without baggage and spent about one and a half years before and parallel to the house construction to get an overview and choose the new items. This process gave us a lot of joy in life. We gave away, sold, or threw away over 70% of the other things and only took what we needed and what brings us joy.

My husband and I will take all old/previous furniture with us. Is that still contemporary or somehow odd nowadays?

Of course, it is still contemporary to take everything with you; there is no either/or. It is also a question of your relationship to your own furniture and budget flexibility plays a role.

The rest will then be newly purchased because often there is more space in the new house.

In terms of floor space, number of rooms, and storage space, we have significantly downsized because we no longer have a separate bedroom, no guest room, and 2 fewer cellar rooms. At the same time, the living space has become significantly more generous. The two children each got an independent one-room apartment instead of children's rooms and can live independently if they want.

Almost everything taken along. Kitchen, dining table, chairs, and wardrobe are new. Some things have aged or are too small, but we want to replace them when the little one is older. Until then, I don't mind if she uses a sofa like children do, or if there is a scratch or child safety lock on the wardrobe.

We are taking everything from our 2-room apartment to our (hopefully) 4-room terraced house.

Prospectively, within the first few months, a new couch (which is overdue anyway) and a dining table (we don't have one yet).
Otherwise, everything stays the same for now.
Certainly, a sideboard or something similar will be added here and there.

Our bedroom furniture is completely from Ikea, 5-10 years old, and all still in very good condition. And very importantly: we still like it.
So there is no reason to buy everything new across the board.
It would be neither economically nor ecologically sensible.

we have downsized from 5 rooms and a basement to 3 rooms without a basement, the new house was planned with the existing furniture and there is still space to rearrange the furniture or make new purchases

Some things we will take with us, for others that could already be renewed now, we will wait until the move.

For example, our daughter's room, everything Ikea Stuva and in use for 10 years. Slowly the child is naturally changing and the house will have a "normal" room then, no pink cupboard doors etc.

Otherwise, our taste has simply changed in some things, so we are also using the opportunity of the move to replace one thing or another, even if it would not yet be necessary.

We mostly only had junk, but still took it with us because time and money were lacking. Besides, you have to see it first and then buy it gradually. After a few years, we have now replaced most of it.
