Due to a combo of a tossing and turning husband who also works shifts, and trying umpteen neck pillows/mattresses over the years, and still waking up stiff and sore (mostly upper back and shoulders) I switched to a hammock and hammock stand combo 3 months ago. Bed is still there though, for "extracurriculars"
lol! (Apparently extracurriculars are possible so they say).
Interest in that was triggered by recalling how comfy the outside hammock is for me, antecdotal evidence I have seen on the web of back pain relief, and knowing people camp outdoors in these things. And I figure people in tropical countries who have slept in these things instead of beds for millenia can't be wrong.
Our current bed is a pillow top tempurpedic and anytime I have gone back to it long enough to sleep for an entire 8 hr night i can feel a HUGE difference! Mattress feels like a rock slab now, even though I do prefer firmer over soft mattresses. If you get in a hammock just right, you feel like you are floating and have no pressure points. Key is to sleep at a 30 to 45 degree angle and for a single person get what is termed a DOUBLE wide hammock (mine opens to 5 ft, I am 5'7 ft) so you can turn (this man demonstrates how I basically crawl in, switch to sidelying, although his hammock is wider than mine. For rolling to other side I just push a foot in and flip, not change head direction).
My setup is below...Brazilian hammock and stand combo from Hammock Universe (Canadian company), and was under 250.00 total. Stand is 9 ft long and lower floor bars about 4 ft wide. People do bolt hammocks in ceiling joists or wall studs with special kits, but did not want to do that though or tinker with the hang angle....my trees outside were bad enough to figure out, plus we have indoor room for this.
I can sleep on my side and the fabric supports my back with no pillow needed back there. Fabric is traditional loom woven and strong, and is not nylon-ish like a lot of camping ones are. Have a small rectangular Ikea couch accessory cushion for under/between knees, and under small of the neck, plus a wool blanket. One word of warning, you will have no insulation of the mattress under you so may need to buy an "underquilt" like campers do (expensive), but for my purposes only being indoors I just wear warmer pjs/long johns, and wool socks but normally need to sleep fairly warm even in a bed.
I will say that I am a convert to this now, but it is not for everyone though and if you want to try it, keep your bed for a backup!
