I have one, it's electric, I raise the head and I slide down so I didn't care for that. it worked fine for raising the bottom part.

However, I got rid of it and bought me a good memory foam pillow and it works for me. I also got rid of the mattress , had a piece of plywood cut for the bed and bough a good firm mattress.

It may work for you, I would rent one first before I bought one. Try it and see because they are expensive. Just sayin'

I use wedge pillows for our bed. I have to keep the head of the bed up because I also have reflux. They work very well and the good ones only cost around 30.00 !

I use a 7" wedge (7"h -30"w- 34"l ) . It folds in half when not in use and very light weight. I had a 12" high, but that was too high and kept sliding down. It also comes in a 3" high too. I would try a wedge, before purchasing a bed, as grannie mentioned the beds are very expensive. Depending on how much height you need to sleep, I would try something like that. Very inexpensive on Amazon.

I also use a wedge pillow, and sometimes another pillow on top of that. I have known some folks to also put maybe a 1-2 inch flat rock or something under the front legs of your bed frame, which will bring it up a bit. I agree, to rent one before you shell out all that money, or try the pillows thing.

you can also get wedges for the legs of the bed to raise to the height you require. Check online but the last I heard you could get them at Walmart.

There is at least one person on here that I know used them and was happy with the results.

i just bought one last month.
i didn't go looking for one, i had gone because i wanted JUST a new mattress (and was ready to spend a lot to get good mattress)
i knew i didn't want that tempurpedic memory foam crap---i can't stand that!
i wanted a good ol spring mattress

it turned out the new mattresses are made so they can do the adjustable bed!
so after i found a mattress i liked; i bought the electical part seperately
(oh mine is queen size, different size mattresses different prices of course)

i love mine & it's just like a hospital bed.
electric & buttons to raise both head & feet at once
or
head only
or
feet only.

just height of bed is stationary.

my whole set (including mattress pad) was around 1900.00 and so far i love it! (they gave me a in store "coupon"---the electric base separately was $800.00---that included delivery, set up etc)
i have 120 days free trial to return either for any reason
mattress has 25 year warranty
adjustable has 20 year warranty

BTW: i had looked at "other stores" and found they were rip offs.
i went to a furniture store with a good reputation in our town & they turned out cheaper with better warranty, so be sure to shop!

PS. if 2 people sleep in the bed there might be some disagreements on who wants it what angle---the king size has each side seperately controlled (i didn't price that, as i didn't need that)

i also tried the wedges & hated them, because sometimes i like sleeping on my stomach & the wedges seemed ackward & in the way so i had tons of pillows on my bed that were easier to toss away; this has eliminated that.
if you sleep in just one position those work, but i'm constantly re-adjusting myself all night trying to find comfortable positions.
this adjustabel bed helps me do that (& i've learned to 'feel" the control buttons in the dark so i can adjust without a light on LOL)

I needed a new mattress and did some on line searching to decide which type of bed would be best. I ended up getting the Amerisleep adjustable bed, free delivery and set up package. Head and feet adjust along with a massage. Its a nice comfortable bed. Very pleased with it.

zeli---i passed on the massage option; now i''m wondering if i should have gone gung ho---how do you like it? & how long have you had yours?

i did serta; and base looks just like the ones in your links.
this link has a "quiz" people can take to see what kind of mattress they may like best....i did this quiz "after the fact" but funny, it showed i should have picked the mattress that i did (so i must have done something right :)

Jarca...I have had the bed for a almost a year now. I loved it and do use the massage option. This is the link that I looked at before buying.

I find I get the best nights sleep in a recliner. Haven't slept in a bed for a while now.

We have a temper-pedic adjustable bed. We like King size, so we got two extra-long twins, with separate controls. We use EL-Twin bottoms sheets, and king size top sheets and blankets. Works great, and we can have the position we each need. I don't slide down, because I can also raise the feet.

Val, I have not been able to lay flat for years. I bought myself one of the large 45 degree wedge pillows to elevate myself. Between the wedge pillow and 2 additional pillows for my head I can rest comfortable. I have not looked into an adjustable bed yet, and as long as I can be comfortable with the wedge I will continue to do so. Also I sleep on my side and not my back. But if the time were to come that the wedge didn't allow me to sleep I would most likely look into an adjustable bed. Take care, Bill
