When it comes to buying big ticket items, like a sofa, don't do it alone! Pick it out with your partner. Not only will they be using it, too, but they may have some ideas or suggestions that you might need to hear before you spend the money.
Facts First - Before you shop at all, you need to get all your facts together first! Measure the area you want the furniture piece to go, measure how to get it to that spot (doorways, stairs or other obstacles). Find out about delivery costs or how you will get that sofa home yourself. Find out how much it will cost to clean or what other kind of maintenance certain materials will take, and what you will be using it for. You don't want a super expensive hard to clean fabric in a super used area that may get frequent spills or stains!
Online Options - If you are looking online first, be sure to do it together! Hearing what is important to you and your partner will help narrow down the decision you need to make possibly a bit quicker. Nothing like finding a bunch of options on your own then finding out that most of them won't work for both of you.
Décor Preferences - Take into consideration both of your décor preferences because no one likes to be left out! You want the piece to last for as long as possible and if one of you hate sitting on a certain fabric now, that won't change after having the item for a while. Neither you nor your partner want to hate a piece of furniture so much that you never use it at all. Learn to compromise with each other so that both of you love the piece you buy and enjoy using it for years to come--together!
Consider How You Lounge - Think about how you want to relax on a sofa or how you like to sit and read, or how high you want a table to be while you eat. Pay attention to how you use your current furniture, so you will know what will (and what won't) work with your new purchase.
You and your partner might struggle with agreeing on what needs to be in your home. If you both consider each other and what works for each of you first, you will have less issues after you both compromise and find that perfect piece of furniture together! Your partner (just like that perfect sofa) will be the center of your life for a long time, so, make sure you have the right fit for all parties involved!
