A king size mattress is one of the bigger purchases you'll make for your bedroom. Get it right and you'll sleep well for a decade. Get it wrong and you'll feel it every morning. This guide covers what to look for, how to compare options, and how to find genuine value — not just a low sticker price.
A standard king measures 76" × 80". A California king is 72" × 84" — narrower but longer, better for taller sleepers. Before you buy, consider:
If you're unsure whether king or California king is the better fit, our showroom teams can walk you through the difference in person. Find a location near you.
The type of mattress matters as much as the price tag. Here's a practical breakdown:
| Type | Best For | Tradeoffs |
|---|---|---|
| Innerspring | Budget-conscious buyers, back/stomach sleepers, hot sleepers | Less pressure relief, can transfer motion |
| Memory Foam | Side sleepers, couples with motion sensitivity, pressure relief | Can retain heat, some feel "stuck" |
| Hybrid | Most sleepers — combines coil support with foam comfort | Heavier, often costs more |
| Latex | Natural material seekers, responsive feel, hot sleepers | Higher price, heavier weight |
| Pillow Top / Euro Top | Plush feel seekers, side sleepers | Softer top can compress over time |

Firmness is personal — but your sleep position narrows it down quickly.
Couples who disagree on firmness have two good options: a split king (two twin XLs side by side, each set to different firmness) or a medium-feel mattress that works reasonably well for both.
See our full mattress collection filtered by feel, or ask a sleep expert in-store to help you narrow it down.
A low price isn't the same as good value. Here's what to evaluate before buying:
More comfort foam isn't always better, but less than 2–3 inches of quality comfort material often feels unsupportive or thin. Look at the full spec sheet, not just the total height.
More coils generally means better contouring and motion isolation in a king. Look for individually pocketed coils if motion isolation matters to you.
A king mattress with poor edge support loses usable sleeping space. If you or your partner sleep near the edge, this matters.
A mattress is a long-term investment. A 10-year warranty minimum is standard. A sleep trial (like our 120-Night Comfort Guarantee) lets you actually sleep on it before committing.
Brands like Tempur-Pedic, Sealy, Stearns & Foster, Diamond, Spring Air, and Englander have a track record. Unknown brands with deep discounts often cut corners on materials or durability.
White glove delivery — where the team brings it up, sets it up, and hauls away your old mattress — is worth something. Ask before you buy.
No photo or spec sheet replaces lying on a mattress. Give each mattress at least 10 minutes in your actual sleep position. Bring your partner if you share a bed. Our 5 LA showrooms carry a wide selection you can test in person. Find the closest location.
The best times to find genuine deals on king mattresses are:
Check our current sale collection for ongoing deals on king sizes.
Splitting a king mattress purchase over 12–24 months interest-free makes the math easier without forcing you to compromise on quality. Ask about financing options in-store or online.
Cooling covers, smart sensors, dual-firmness zones — these features add cost. If you sleep cool and don't need specialized features, a well-built hybrid or foam mattress at a mid-range price will outperform a feature-heavy model at the same budget every time.
Stop by any of our 5 LA showroom locations to try king and California king mattresses side by side. Our team can help match you to the right feel, brand, and budget — with no pressure and no upsell.

A standard king is 76"×80" — wider and better for couples. A California king is 72"×84" — narrower but 4 inches longer, ideal for taller sleepers. They also require different sized sheets and bed frames.
A solid king mattress from a reputable brand typically ranges from $800 to $2,500, depending on the type and materials. You can find good value in the $1,000–$1,800 range without overspending on unnecessary features. Premium options from brands like Tempur-Pedic or Stearns & Foster go higher.
It depends on your bedroom size and sleep habits. If you move around a lot and have the room for it, a king can feel luxurious. If your room is tight, a queen will often serve you better.
Yes. Standard king and California king require different frame dimensions. Make sure your frame or adjustable base is rated for king size before purchasing. We can help you match a frame to your mattress.
For couples with different firmness preferences, a medium-feel hybrid usually works well for both. If motion is an issue, look for a mattress with individually pocketed coils or a full-foam design. A split king (two twin XLs) is the most customizable option.
