King Koil Mattress Ratings

The report below is based on 80+ King Koil and Laura Ashley innerspring mattress owner experiences for various models such as Spine Support and Posture Sense.

Owner satisfaction d King Koil innerspring mattresses overall (including Laura Ashley) have 63% owner satisfaction. Learn more.
Durability / longevity d+ Like innerspring beds overall, King Koil's lifespan is below average compared to non-innerspring beds. Owner experience data suggests King Koil beds will sag to an extent that undermines comfort and support within 3-4 years for at least 20% of owners. (Extended Life is a King Koil model designed to have superior durability, but owner experience data for this model is currently lacking.)
Affordable B- The price range is $250-$2,700 depending on size and model, not including a foundation.
Less pain c See mattresses and pain relief for general analysis.
Motion isolation c+ A mattress has motion isolation if it absorbs movement from one sleeper so that the other sleeper is not disturbed. King Koil motion isolation can vary from poor to good depending on the model. Those with independently encased (pocket) coils tend to perform best.
No initial odor / off gassing b- Initial smell from most King Koil models is not a significant problem.
No sleeping hot b- Less than 5% of owners report a heat retention issue.
Good for sex B- Mattress sagging can be detrimental in regard to this issue. (See mattresses and sex for general analysis).
No noise c Models that use a coil system other than independently encased (pocket) coils may make noise, such as squeaking and creaking.
Low maintenance c Most models are no-flip. At least 10% of owners report having to regularly rotate their mattress (head to foot) to combat sagging and body impression development.
Specs disclosed C- King Koil performs about average at providing specifications for its beds. Information regarding thickness measurements for the various layers as well as details on the makeup of the materials is often not available. This lack of information can hinder making an informed buying decision as well as comparison shopping.
Availability C There are many King Koil (and Laura Ashley) retailers on the East Coast, somewhat fewer in the Midwest, and few on the West Coast.
Warranty c The beds have a 5-20 year warranty depending on the model. (See mattress warranties: what you should know.)
Customer service B- The helpfulness and politeness of customer service has been questioned by at least 8% of owners included in our research.
Better Business Bureau (BBB) rating a+ King Koil has an "A+" rating. It has had only three complaints filed against it in the past three years (one in the past year) which is much better than average for a mattress company of its size.
Sleep Like The Dead (SLTD) Rating C+ SLTD rating of "C+" for King Koil is based on several factors including product ratings by consumers, years in business, customer service, accuracy of marketing claims, transparency of specifications, warranty, BBB rating and rating stability, number of BBB complaints / business size ratio.
