Best bed I've owned

I absolutely loved this bed. I received it slightly second hand, it'd been a guest bed that had been purchased new not long before we received it. It was perfectly firm yet soft in that now matter how you slept it contoured your body and supported your spine perfectly. It kept cool didn't transfer movement between you and another. The thing held up nearly 13+ years, went through 3 to 4 moves. I just had to get rid of it this year due to it literally crumbling from the outside. It wasn't it's fault though. It did it's time and deserved it's retirement. If you're presented the chance I highly recommend the purchase of this mattress. I cannot overstate the many years of sleep they provided me.

This mattress needs to be renamed the Coma

Absolutely love this mattress I sleep more sound than I have in years. I’ve told my husband we will call it the coma.

Wonderful mattress!

We purchased the King Koil Sunset mattress from a local store and have had nothing but great sleep in it for the two years we've owned it!

Warranty is useless!

This is my second king koil. The 1st one I had 15 years was amazing. I upgraded to the most expensive this time and it’s been horrible. I’ve tried to get the manufacturer to replace it and they have been no help. I will never buy from them again. So sad that they have so little care for their customers or pride in their product.

Outstanding!

Never thought we'd spend close to $10000 for a bed but when we tried out the "Smart Life" split head mattress in the showroom we were amazed how comfortable it was. When we laid down we were surprised to find it had "body sensing technology" which recognized our sleep position changes during the night that subtly adjusted the silicone cells according to our pressure points. The bed has an incredible massage mode we use every night as well as other massage options. We have the adjustable bed frame and a split mattress head so we're able to raise/lower the head and foot of our bed independently so we're able to sit up to read or watch TV without bothering each other. This feature has benefited our various health conditions, i.e., sleep apnea, allergies, etc., during the night. All in all, we definitely made the right choice and highly recommend this mattress and bed frame.

Great mattress

Many back and hip problems. No pain and great sleep. Anyone who lays down on it goes to sleep. Visiting relatives and especially children. Highly recommend.

Sagging within a month

Deep sagging in the center within a month. Horrible support. My 10 year old mattress was better than this new one a month in

Had mattress inspector. No help from him.

Any mattress that sags in the middle when laying is not comfortable. It does not have a 1.5 inch dip in the mattress, so it was not replaced.

HARD not soft!! Shoulders hurt like hell!

I had a pillow top for many years and never had a problem. This bed says it's soft but it is not. Quite firm!! I suffer from arthritis tendonitis and bursitis in my shoulders so if you have anything like that don't get this bed. Also have back problems but my shoulders hurt so much I cant even remember about my back right now. 🆘

What a rip!

I purchased this bed from Sleepy's some years ago and it was quite expensive (over $2000). Had it delivered to my home and set up. For about a month, it felt great. Felt comfortable, supportive, didn't sleep hot. After a while, though, I started to notice it was sinking on both sides, in the places where my partner and I sleep, with a noticeable "hump" in the middle. Eventually, it was like rolling up a mountain to reach the center of the bed. After less than a year, we quit using it. "Customer service" was totally non-responsive, but because it had cost so much, I didn't want to just throw it out, so it went in the guest room. We are not big people, and certainly did not abuse the mattress. There is no excuse for this shoddy quality on such an expensive item. The Dr. Breus mattress was a total rip-off.
