Have you actually seen the chair in diffenet sizes? I looked at them 4 years ago, and if the stye is the same, they look a lot alike. I could not tell the difference in the show room.

If they are true Stressless they will look very much the same and unless you have them right beside eachother you will not see the difference.

When we bought two new leather chairs for our TV room...one for my husband and one for me, we bought two different sizes...smaller one for me and bigger one for him. Both are navy blue leather rockers and really like the looks of them. The larger chair is a Lane, reclines and swivels and the smaller chair is a Lazy Boy, which rocks and reclines. Lazy Boy is just right for my five foot three inch body.

The size difference is subtle. If the chairs are a few feet apart, you will hardly notice it.

If it is the same STYLE chair you will not notice any difference between the two if one is a small / medium / or a large. But if they are two different styles you will notice the difference. I have 2 different style Stressless chairs next to each other and it had been difficult for me to place them in my family room. But they are 2 different style and 2 different colors. That is the problem. But if you go with the same color and style you will never know that one is larger than the other. Great chairs that are super comfortable!
