King Koil has maintained a deep collaborative research partnership with the International Chiropractors Association since 1969 — ICA chiropractors co-designed the support systems, not just reviewed finished products. The brand also carries the Good Housekeeping Seal of Approval and has been in business for 125+ years, manufacturing its US mattresses in Avondale, Arizona. Shop King Koil at Sit 'n Sleep across locations in Los Angeles, Orange County, Riverside County, San Bernardino County, and Ventura County — available in Culver City, Laguna Hills, Torrance, Brea, and Norco and across Southern California. If you're searching for a King Koil near you in Southern California, use BedMATCH at any location to find the right model.

ICA Partnership since 1969

In 1969, King Koil and the International Chiropractors Association formed a collaborative research partnership — not a standard endorsement arrangement. A council of leading chiropractors worked directly with King Koil's product development team to engineer support systems based on spinal health, pressure point science, and sleep biomechanics. Mattresses that met the resulting standards earn the ICA Seal of Approval. This partnership has been ongoing for over 55 years.

Which King Koil Collection Is Right for You?

King Koil organizes its lineup from accessible hybrid to ultra-luxury handcrafted. Every qualifying model carries ICA-informed support design. The brand has manufactured mattresses in the USA since 1898.

The best King Koil mattress for back pain or spinal support depends on your body weight, sleep position, and budget. BedMATCH at any Sit 'n Sleep location matches you to the right model using 18 body measurements.

What backs the brand

  • King Koil's ICA partnership began in 1969 as a deep, collaborative research relationship — not a simple endorsement. ICA chiropractors provided clinical insights on spinal health, pressure points, and sleep biomechanics that King Koil translated into its support systems. The ICA Seal of Approval is awarded only to models that meet the standards resulting from that collaboration.
  • King Koil also carries the Good Housekeeping Seal of Approval — an independent consumer-protection endorsement from one of the most recognized testing programs in the US.
  • Founded in 1898 in Saint Paul, Minnesota — 125+ years in business. King Koil manufactures its US mattresses in Avondale, Arizona, serving California and the western US. The brand operates in over 90 countries through its licensee network.

Not Sure Which King Koil Fits Your Body?

BedMATCH's 18-measurement diagnostic identifies the right support level for your body — matching you to the right King Koil model before you lie down. Available at every Sit 'n Sleep location, no appointment needed.

Frequently Asked Questions

What makes King Koil different from other mattress brands?
King Koil has maintained a deep collaborative research partnership with the International Chiropractors Association since 1969 — not just an endorsement sticker, but a relationship where ICA chiropractors co-designed the support systems. Every King Koil mattress that meets ICA's rigorous standards earns the ICA Seal of Approval. The brand also carries the Good Housekeeping Seal of Approval. Founded in 1898 — 125+ years in business — King Koil manufactures its US mattresses in Avondale, Arizona, serving California and the western US.
Is King Koil good for back pain?
King Koil's ICA partnership since 1969 exists specifically to engineer mattresses for healthy spinal alignment. ICA chiropractors worked directly with King Koil's product development team to define how support should be distributed — firmer in the center third where most body weight applies, with appropriate cushioning at the shoulders and hips. Every King Koil model bearing the ICA Seal of Approval has been evaluated against these spinal health criteria by a council of chiropractors. Use BedMATCH at any Sit 'n Sleep location to identify the right collection and firmness for your body.
What is the ICA endorsement and why does it matter?
The International Chiropractors Association is a professional organization of chiropractors focused on spinal health. King Koil's ICA relationship began in 1969 as a collaborative design partnership — chiropractors provided clinical input on pressure points, spinal alignment, and sleep biomechanics, which King Koil translated into its support systems. Mattresses that met the resulting standards earned the ICA Seal of Approval. This is a more substantive relationship than most mattress brand endorsements, which are typically review-based rather than co-development based.
Which King Koil mattress is right for me?
King Koil's lineup covers five collections at Sit 'n Sleep. The MHybrid uses advanced memory foam over the Perfect Contour Reaction coil system for a modern hybrid feel. The Xtended Life is built for durability — zoned encased coils with layered foams designed to perform year after year. PureBliss uses hypoallergenic Talalay latex with graphite for natural cooling. The Intimate Collection is the luxury tier — hand-tufted with Joma wool, Talalay latex, and micro coils. The Reserve Luxury is King Koil's flagship — over 1,000 hand-assembled coils, horse hair, merino wool, and graphite latex, all handcrafted. BedMATCH at any Sit 'n Sleep location matches your body to the right support level in about 20 minutes.
Is King Koil worth the price?
Yes — King Koil sits in the mid-to-premium range and offers meaningful differentiation through its ICA partnership and Good Housekeeping Seal. For customers who specifically want chiropractor-informed support — not just a brand claim, but a co-developed product standard — King Koil is difficult to match at its price point. Sit 'n Sleep's 120-night comfort trial means you can verify the feel and support at home.
Where can I try a King Koil mattress in Southern California?
Sit 'n Sleep carries King Koil mattresses across locations in Los Angeles, Orange County, Riverside County, San Bernardino County, and Ventura County. Every location offers BedMATCH diagnostic fitting to match you to the right King Koil model. Find your nearest store — no appointment needed.

Frequently Asked Questions

When should I get a new mattress?

Mattresses typically stay in top condition for seven to 10 years. Telltale signs that it’s time for a trade-in include: aches and pains, sagging, edge collapse, and other signs of wear and tear.

Should I replace my box spring when I buy a new mattress?

Yes, it’s best to purchase both together. Most newer mattresses only have one sleep surface, so they need different box springs than your old mattress would likely have. You also may need to get the box spring for the warranty to be valid. 

How much should I spend?

 

That depends on your price point and the types of features you are looking for. King Koil mattresses are available at a wide range of price points.
