Buying a “Sofa set” is one of the most important investments you are likely to make for your home. In the living room it’s a piece for lounging, reading, eating, amusing, watching television, and indeed napping, so it makes sense that we take the time to invest in one that is going to last for times to come. You know when you are on the quest for a new mattress and you do the age-old bottom test? The same proposition applies to a lounge. The average sofa has a seat depth of at least 60 cm, which gives plenitude of room to maneuver if you have long legs and allows you to tuck them under if you are shorter. But seat depths do vary, so surely try out different styles to ensure you get good back support. When it comes to seat height, the utmost designs are between 45 cm and 50 cm high. There is no right or wrong height, so again, try before you buy to make sure it suits you.
