Trestle tables can give you flexibility along the sides of the table, but can limit space at the ends of it. Look closely at how much space there is between the edge of the table and where the trestle supports are attached to make sure there’s room for your knees.
It is likely that you will take the new items with you and so it wont be a wasted spend and could end up selling your home if it helps to make the room appeal to buyers. If you dont take them with you and the buyers like the space, you could offer to sell them - this is particularly handy for first-time buyers.
The advantage of a glass-top dining table is that it works well with many decor themes. And because it has a reflective surface, it is an excellent choice for a space that might need to look a little lighter and brighter.
If you are looking for a table to suit an urban-industrial decor theme, don’t go all-out with a (heavy) metal table but consider a (lighter) wood table with some metal design features.
