Learn many ways to be comfortable in meditation, in the houshould you can sit anywhere and being comfortable is extremely important.
The easiest way to sit in meditation is in a dinning chair with a comfortable cushion place under your behind, as your mind will realize that if you fall asleep you may fall and pain ensues, not that it will happen just your mind will have that fear, it also is a great posturing position as you can use the chair to help keep you spine straight and your body upright using the chairs ergonomics to sit.
Another way to sit during meditation is to use a large cushion on the floor, either sitting crossed legged or kneeling, which ever you are comfortable with, this requires some balance and practice to go into a meditative state and not fall over during your meditation and if you fall to sleep it's not a long way down to the floor, with this posture setting you can also do intermediate to advanced meditations to achieve a higher state of meditation.
You can also sit your favorite lounge chair doing your favorite meditation, with a candle lit, this is especially great on a cold or wet nights, to add comfort to meditation experience, this is my personal favorite as it is comfortable it allows my mind to either focus or wander, it gives me the freedom to experience, if you are lucky enough to have an open fire place even better, you can focus on the crackling fire.
To combat fatigue in any posture setting no matter how comfortable you may be, you can use stress balls or crystals by placing them in the palm of your hand, slowly roll them in the around in a clock wise position, though do not allow the balls or crystals be a part of your focus, instead focus on your breath or on any meditation task your are approaching.
Using theses techniques in meditation can benefit you in your everyday life, your posturing and comfort are an important part of seated meditation and should always approach posturing in a extremely selfish manner as meditation is about you and you do need to look after yourself in every possible way you can, being comfortable in your seated position in important to achieve a meditative state, make sure your meditation experience is enjoyable by being comfortable.
