Sit up seat for solids!

Sunny

We had our appointment yesterday and the doctor is giving us a yes on starting solids. Any recommendations for tried and tested sit up seats. Baby has to be seated to be given the solids. She said the bumbo but a lot of reviews say the thigh area is not too comfortable. Keeping in mind we have leather dining room chairs so I don't know how well something will strap on to them without messing them up. Please help!
