I'm new to this forum but I saw your message on my Dollar Stretcher newsletter and just had to respond.
I've had a queen size adjustable bed for about 2 and a half years now. And I LOVE IT! Mine is a Tempur Pedic adjustable bed so part of the reason I love it is the Tempur Pedic mattress. But I did try other beds before buying this one and learned that the mechanism that makes them adjustable is generally made by one company - Leggett & Platt. They make a good product (and they are really the only ones who do) but it's not perfect.
Here's what I know.
Shop when you have time. Don't just sit on the bed for a minute or two. Lay there for 20-30 minutes in the position you plan to sleep in. If the sales guy rushes you, leave the store. We spend a third of our lives in bed and you deserve to be comfortable. Don't be shy about taking as long as you need.
Try the Tempur Pedic mattress but only if you weigh more than 150 pounds. These mattresses seem to be a real problem for skinny people. I think it's because they never sink down to the special layer of memory foam that makes Tempur Pedic so special. Also, these beds cost more. A lot more. But if you have a doctor who can "prescibe" the bed, you might be able to get some insurance thing to pay for a part of it. And they are worth every penny, in my opinion.
Try all the beds available in your area. All the different brands. Because your body is different than anyone elses and you need to be comfortable.
Make sure the base is Leggett & Platt. They are really the only ones making good quality bases these days. Knock off mattresses can be OK because it's a pretty basic thing but the base is what you will use to raise and lower the head & feet every day so it takes a lot of wear and tear. If it isn't a L&P then search the maker on the net thoroughly before you buy. There may be different makers in your area but I did a lot of research before I bought and L&P made all the bases for the beds I looked into.
Be prepared for the occasional repair. Make sure that you find out who does repairs in your area and get a warranty for as long as you can on the base. These are mechanical devices. There are wheels and cogs and a motor and stuff that can break down. Repairs are really inevitable. Even extremely pricey hospital beds get repaired sometimes. It's unavoidable. So you want to be prepared.
Try and get a 30 day trial period before you buy. Lots of places will let you return the bed if you aren't happy after 30 days. I say this because it can be an adjustment actually sleeping in one of these beds. And they aren't for everyone.
You'll definitely need to keep your knees raised at night a bit if you have your head up. If you don't, you may find that you develop hip and lower back problems. Mine has a couple of pre-sets on the remote. One of them is just about perfect for me. It raises my head to about a 60 degree angle and my knees up just enough to take the pressure off my lower back. It's like being cradled by the bed. My only problem is getting out in the morning because I'm so comfy.
You need to lower the bed before getting in and out of it. The owners manual may not be clear on this but it's very hard on the cogs and the machinery of the base if you are climbing into the bed while it's raised. You also don't want big kids or dogs leaping on the bed while it's in the raised position. And if you are having a "romantic encounter" (lucky you!) the bed should be flat then as well.
It will come with a remote so you can raise and lower it. Frankly, it doesn't matter if it's wired to the bed or not. You'll be using it from the bed all the time so it really doesn't matter.
Don't pay extra for massaging/vibrating options. You won't use them. And you can't use them while you are asleep because then the motor would run all night. Very dangerous.
If you have GERD I highly recommend an adjustable bed. If you can get your doctor to say you need one you might get a little help from your insurance company. I don't know where you live or what insurance you have so you'd have to check into this on your own. But it's worth asking before you buy.
I also have GERD and while I do still have to take medication for it, it's been a whole lot better since I got the bed. They are also great for people with back, hip and knee problems.
I think that's everything. But feel free to ask. If I can help, I'm happy to.
