Input:
Question: Does the head of the bed come all the way up to a 90 degree angle? I like to sit up very straight in bed when I read, etc.
Document: The frame, although heavy, was easy to put together and it seems to work well. My only problem is this: I am 5'10&#34; tall. The upper part lifts me up fine, but the design has my feet off the end of the bed when I am in a more upright position to watch TV or read. There are several inches of extra head space so the &#34;folds&#34; could be better placed.
I have never had a sleep experience like the one I had the night my bed arrived! My sister and I put it together in 30 minutes and I love my new bed!! !
Once assembled this bed does work very well and theassembly is, indeed very straight forward and canbe done easily.
The XL Twin bed base worked perfectly. It only took about 15 minutes to unpack the two boxes and assemble it. We used it with our existing foam mattress, and it is very comfortable.When it's flat, we don't even know we're on an adjustable bed: there is no sag at the ends, and it feels like a solid platform bed.
In addition, getting the motorto lock on to the hinge like things on the cross barwas not easy.But I figured it out and the unit does work great.
Amazon comes through once again. My wife and I have had back surgery's and after spending allot of money on pillow top beds that failed over a short time, we decided on two twin XL memory foam beds with the Leggett and Platt adjustable base's. We have had our adjustable base's for about a week. UPS delivered them to our front door and set up was very easy and quick. Its so much better not having to stack pillows just to sit up in bed. The motors are so quite.
This was my first upgrade to an adjustable, and that's a big part of the value for me. Having read all the reviews I could find, I was pleasantly surprised by the ease of assembly. Legs could go a little higher, for my own preference. But I am sleeping much more comfortably and soundly, and this has helped mitigate both asthma and sciatica issues for me. Got one for my 85 year old mom, and she can use the simple remote.
The bed was exactly what I needed the link the height was a lot better than Craftmatic's I can put stuff under the bed now it operates beautiful very much.
I ordered this for my mother who has trouble with back and knee pain. She says that this bed has helped her tremendously. She claims she wakes up without knee pain.
My husband has COPD and has found this bed extremely beneficial. I also have one that I occasionally adjust for reflux. We set them side by side with a king size top sheet and bedspread...works great!
Answer: No. I would estimate 60 degrees
