Great for 8 years

My husband wants to buy a new mattress as he feels he’s worn this one out despite rotating regularly

Poor quality and warranty not worth the paper!!!!

DO NOT BUY a Kingsdown Mattress!!! I purchased a new Kingsdown King size mattress in June 2018. Within months of owning the bed it began to sag and created a hump in the middle. After contacting Kingsdown for the warranty, they sent out a third party inspector who indicated the mattress had a 2” dip on the right side. Kingsdown denied my warranty claim stating it was within normal wear measurements. Now, if anyone else is considering spending over $1,500 on a mattress, I’m sure you’d like to ensure you have a product that lasts for more than a few months and the warranty is valid. Nice job Kingsdown you lost another customer!!!

Terrible!!

Completely disgusted with this company’s warranty! My husband and I purchased a Kingsdown mattress exactly 8 months ago after my husband had back surgery. It was specifically asked and promised by the sales rep at Teppermans Windsor there would be no dipping at the lower lumbar area. We spent over $4000 on a king size custom number bed. Well Kingsdown....it’s dipping a lot and we are normal size people. Can’t even imagine what this mattress would look like if we were over weight people. Teppermans keeps saying you won’t cover the warranty because it’s “normal” dipping. NO MATTRRSS AFTER 8 MONTHS SHOULD SINK/ DIP! I don’t care if it’s 1 inch or 1.25 inches of dipping ...it’s dipping without body weight on it. To add to insult the company actually put a piece of plexiglass on top of the mattress to do their measurements! Are you kidding...how is that going to give you a true concave measurement when your applying a flat surface. If you stand by your products.....maybe you should stop fighting customers and fix the issue!!!! Prior to this purchase I had a mattress that was over 14 years old and never had the issues I’m having now after 8 months! I still have that mattress as well! Maybe I should have went with that company instead....at least nothing dips! I’m not rich so it’s not an option to buy another one! Fix the problem KINGSDOWN if you have any integrity!!

I’d buy a new cheap one every year

The mattress was good for a few years maybe two and then it begin to separate on the sides and impressions and warranty company stated because there was a small sweat stain that it void our warranty and now we have a really expensive garbage bed

Body impressions after the first year no help from Kingsdown

Their warranty has got to be the worst in the industry. There is no understanding from them. They are in business for the money Not the consumer. Never buy a Kingsdown. If you do have problems, they are not there for you.

Kings down

I bought the Kingsdown in June 2010, within months it started sagging. Now the seams are spitting open. Called customer service, I was told that the fabric is not under warranty, I tried to explain to them that it's not the fabric, but the seams are coming apart. I was told that they would send someone to patch my mattress.

Kingston Bed is slanted on one side

We bought a kingsdown mattress. I noticed that one side seemed slanted and I felt like I was rolling off the side. We had a inspector come out from Kingsdown who indicated that the bed was in fact 1" lower on one side of the bed. You can actually see the hump in the middle. We received a letter from Kingsdown that we were denied our warranty because the bed needed to be 1.5" lower at a minimum to be covered by warranty. So much for standing behind their product. Thumbs down for Kingsdown.

Tear in latex just after 9months!

After several months of searching for the right mattress and going through two separate mattress returns with our furnture company, we finally settled on a Kingsdown Dual Mattress (meaning each side has a different level of comfort and support.) We absolutely loved it. Over and over again, we commented to each other about what a great mattress this was. But then after 9months of ownership I woke up one morning feeling a tear in the latex top. Underneath the fabric cover there was a clear 6 inch tear with spring coming up through it. I could not believe it! What made it worse was since I bought it on clearance, there was no warranty. Well it was great while it lasted (only 9months)! Needless to say, I am very dissappointed, Because we loved the comfort of this mattress, I am thinking about somehow repairing it myself.
