How much space do I really need in my bedroom for a king mattress from Best Buy Furniture?

To comfortably fit a king mattress (76" x 80") and have space for nightstands and walking room, we recommend a bedroom that's at least 12 feet by 12 feet. This gives you enough room for the mattress and easy movement around your bed.

What types of king mattresses do you offer, and how do I choose between firm, plush, memory foam, or hybrid?

Our King Mattress collection includes memory foam, innerspring, hybrid, and natural latex models, with options in plush, medium-firm, and firm. If you sleep on your side, you might prefer plush or medium. Back and stomach sleepers often do better with medium-firm or firm. Hybrids are great for cooling and balanced support, while memory foam is excellent for pressure relief and minimal motion transfer.

How does the 120-night sleep trial and free return policy work for king mattresses?

You get 120 nights to try your new king mattress at home. If you’re not sleeping comfortably, contact us and we’ll handle pickup for a full refund or exchange—free of charge. Our goal is to make sure you truly love your mattress, risk-free.

What’s included with the free delivery and setup service when I buy a king mattress from Best Buy Furniture?

We offer complimentary local delivery, white-glove setup in your bedroom, and removal of your old mattress—at no extra cost. For most areas in Philadelphia and New Jersey, we even provide same-day delivery, so you can enjoy your new king-sized comfort fast and hassle-free.

Can I use an adjustable base with your king mattresses, and are split-king models available?

Yes, many of our king mattresses are compatible with adjustable bases. We also offer split-king configurations—two Twin XL mattresses that fit together as a king. Split-king models let each sleeper choose their own firmness and help reduce motion transfer, making them popular for couples with different sleep needs.
