What You Need To Know

THE GOOD: Many Kingsdown models have advanced features, high coil count, and luxurious, conforming materials. Kingsdown's bedMATCH system (available online and at select retailers) creates a personal profile to help you select a proper mattress.

THE BAD: At least 20% of owners report sagging and or the development of body impressions occurring within three years of ownership (a rate similar to that of innerspring beds in general). Some models are pricey and heavy. Customer service is likely no better than fair.

THE COMPETITION: Kingsdown's main competitors are Sealy, Stearns & Foster, Simmons and Serta. See how Kingsdown compares to these and others in the innerspring mattress reviews – summary and the mattress comparison.

THE COMPANY: Like most of its main competition, Kingsdown (headquartered in Mebane, North Carolina) was founded over a century ago. The company manufactures mostly innerspring-based mattresses including models Passions, Downtown Abbey, Sleep To Live, and Diamond Royale.

THE RETAILERS: Major retailers include Mattress Warehouse (sleephappens.com) and Sit n' Sleep. In several markets, Kingsdown mattresses may be difficult to locate.

Kingsdown Mattress Ratings

The ratings – based on owner experience data collected using an unbiased, accurate methodology – show how Kingsdown beds overall compare to the average mattress.

Owner satisfaction d+ Kingsdown innerspring mattresses have 65% owner satisfaction overall. More.
Durability / longevity d+ Kingsdown's below-average satisfaction is due mostly to the fact that 20%+ of owners report sagging / body impressions occurring within the first 3 years – a rate similar to that of innerspring beds overall. More.
Affordable C- $400-$3500+ depending on size / model, not including a foundation. The average queen Kingsdown is estimated to cost $1925. More.
Less (back) pain c+ When the mattress is new, consumers generally report that their Kingsdown has strong comfort and pain-relief potential. But within the first three years, at least 15% of owners report pain, including back pain, due to sagging / loss of support. (See mattresses and pain.)
General support B- Most models have an average to above-average coil count which may be helpful for support. Sagging of the comfort layer(s), however, often undermines support.
Edge support B Support for sleeping or sitting near the far edge of the mattress appears to be at least average for most models.
Conforming ability B A conforming mattress is one that molds and contours to the sleeper's body resulting in a cradling, cloud-like, pressure-point-free sensation. Models with at least one inch of memory foam and or latex tend to rate above average on this issue.
Easy to move on C- Softer, conforming models and or those with memory foam may offer moderate resistance to changing positions and getting up off the bed.
Easy to get on / off D+ Due to the above-average thickness of many Kingsdown models, getting on / off the bed may be challenging for shorter people. More.
Motion isolation b- Models with individually wrapped coils offer above average effectiveness in isolating a person's movement so that another person is not disturbed. Models with open coils do not perform as well. (General analysis: mattress motion isolation.)
No initial odor / off gassing C About 6% of owners report off gassing which is a chemical-like odor a mattress can give off when it is new often due mainly to its foam content. (See mattress off gassing for general analysis.)
No sleeping hot C About 8% of owners report that their bed sleeps hot enough to be uncomfortable. Soft models with memory foam appear to have the greatest potential to sleep hot. (See mattress heat retention for general analysis.)
Heavy person friendly B- Firmer models with a 3-inch or less comfort layer are likely best suited for people 230+ lbs. (See mattress buying guide for large people.)
Light person friendly B Soft to medium firmness models with little or no memory foam tend to be best suited for people under 130 lbs. (See mattress buying guide for small people.)
Good for sex B- Sagging may cause romance to be uncomfortable or difficult. (See mattresses & sex for general analysis.)
No noise B The mattresses can make noise under certain conditions, but the problem is not common. (General analysis: mattress noise.)
Easy to maintain C- Some models have a two-sided design which can be flipped and rotated to extend mattress life. But most Kingsdown models have a no-flip design requiring only rotation about 1-3 times annually.
Easy to lift, handle, move D+ Weight is estimated to range 65 to 160 pounds depending on model and size with the average Kingsdown queen weighing about 120 pounds – at least 20% more than the average mattress. Grips are present on most models. More.

Kingsdown mattresses are often 10 to 16 inches thick with average being about 13.5 inches. While mattresses with at least 11-inches thickness often have a luxurious and upscale presence, they may be too tall for easily getting on and off, especially for shorter people. A low-profile foundation can help to lower the bed's overall height.

The average Kingsdown mattress is significantly heavier than both the average mattress and the average innerspring mattress. This is due mostly to its above average thickness. A heavy mattress has the advantage of staying in place but the disadvantage of being difficult to move, lift and handle.
