I'm not sure...I would go with: the atoms in the chair are strong, so empty space is less important because of the weight distribution. Also, my guess would be that the empty space is mainly in an area that doesn't support your weight.
The newest theory to answer this is applied to "How do the stars and planets hang where they are?" See: Dark matter. It is believed now that it is dark matter that holds things together.
I was watching a show on National Geographic that mentioned atoms being mostly empty space. They asked this question but in the context of a batter hitting a ball. The nucleus of an atom is enveloped by electrons which repel other electrons. They also said that because of this, nothing can actually ever touch: there is always a slight gap between objects. The sensation of touch is actually you feeling the repulsion of the electrons.
EDIT: From what I understand the ratio of empty space to solid space between the nucleus of an atom and it's electron is almost an exact ratio in size and distance of the Earth to the Sun. The electron's rotation is what keeps two objects separate. However, if something were vibrating at an entirely different frequency from another thing, it would be capable of passing right through it. The speed of the electron is so extreme that even light is reflected off of it's surface making an object appear to be solid. There are many theories involving alternate dimensions and realities that vibrate on other frequency ranges, exist at the same time and place as we do, but never affect our reality.
The atoms in a solid are tight and closely compacted together. They aren't liquid, whose atoms are looser than atoms in a solid; nor are they a gas, whose atoms are a LOT looser and spacious.
That is because of electrical forces between the atoms.
A semipermeable membrane.
they have a 'sea' of delocalised electrons in their structure which are free to move and carry a charge through the structure
A kitchen sieve will allow this.
largely empty space
A long chain of amino acids are called a polypeptide, which goes through a folding process to become a protein.
through-composed
Simply stated: ProteinsChannels within the structure of the cell membrane are composed of proteins. A protein that forms an ion channel through a membrane is called a transmembrane protein.
through composed
No, it is mostly composed in strophic and modified strophic forms.
Salt water is coductive.
The main structure of the plasma membrane is composed of the phospholipid bilayer. The phospholipid bilayer is composed of a spherical hypertonic head & a straight hypotonic tail which is designed to prevent the flow of unauthorized molecules & to maintain control of what enters & exits the cell. In order for a molecule to pass through, it must use one of multiple different methods of molecular transportation. The most common is the use of channel proteins. The molecule will travel through the channel protein based on its size & polarity-polar or non-polar.

Strophic and Through-Composed.
It's in through-composed form.
Waves travel through everything, whether they are composed of solidity or not.
In physical terms, the properties of a substance will be determined by its molecular structure. Unlike water-based substances, fatty materials such as oils have long molecules composed of chains of carbon and hydrogen atoms bonded to glycerol. If the chain is disbanded (such as happens through contact with bile or detergents), the fat loses its structure and properties.
