I'd recommend the seventh-generation Volkswagen Golf (launched in 2013). It's a very comfortable family hatch with excellent ride quality and impressive refinement from the 1.4-litre petrol engine. However, a number of owners have experienced issues with the DSG automatic gearbox, so check the good/bad section of our review before you start to test drive some examples: www.honestjohn.co.uk/volkswagen/golf/2013/

Alternatively, if you'd prefer something a bit more upmarket, a used Mercedes-Benz C-Class could be a good choice. Avoid the sportier trim levels - an Executive SE with its standard suspension, regular seats and 17-inch alloy wheels will be more comfortable than an AMG Sport, for example. You could also look at an SUV - a Hyundai Tucson with small wheels will be another very comfortable choice.
