Always receive excellent products Review by EDWARD
Boyds is an exceptional company. I've owned their bed for 16 years. I've replaced the liner on year 10 and just replaced the tubes after 16 years. Looking back I should have replaced the tubes at 10 years like Boyd suggested as I developed a small leak in one tube. Not a serious problem as the liner caught the small amount of water. I was happy to see the quality of the tubes look to be as good as the originals. This King bed with foam filled water tubes is still the most comfortable bed I've ever slept in. We have tried beds that cost $1000's of dollars more but nothing compares to our $700 bed. After 42 years of marriage anything to make your life easier is a bargain. Thanks Boyds for your quality product and reasonable pricing. Shipment of orders are always fast. P.S. It's important to put in new water tablets regularly as it not only keeps the water clean but keeps the vinly tubes soft so they last longer. I must admit I didn't do it yearly like recommended but had good results anyway. (Posted on 4/1/2017)
Purchased new set of tubes Review by Restful sleep
Having slept on floatation waterbeds since 1989, I can say it's the most comfortable rest you will find. I've owned 2 California Kings and a Queen size floatation, always with the baffled filling. After 21 years with the same CK tubes, one began to have a small leak. Best to replace them all at the same time. I also replaced the mattress liner too as it was also the same age. My only criticism is that the smell of plastic is very strong. I did not experience this with the other tubes/beds. (Posted on 9/11/2016)
