Lower back pain/pelvic tilt /mattress suggestions

I tried a memory foam pillow and found it hard as a rock. The catch, I think is room temperature. My basement bedroom is at 65 F during the day and drops a degree or two overnight which makes memory foam hard and inflexible.

I have a non-memory foam plush mattress topper to try to reduce the harshness of my mattress on order.

Yes. Your body weight in different places makes the mattress firmer or softer in spots. Example if you sleep on your side, your shoulder will likely press on the mattress so the air adjusts accordingly. I highly recommend you visit their website for a better explanation. sleepnumber.com.

The foot warmer was included in my bed. I know we spent mucho for the bed, but in the long run it’s corrected our infirm issues

Thanks for the info. I'm going to find out if they have a store/showroom within decent distance.

Thanks for the info. Memory foam can be "tricky" and both of us have found it to not be of much help.

Yes, the Beautyrest Memory Foam Classic Series. I tried a softer mattress and it was too soft and incredibly warm. I sent it back and got the firmer one. It is so hard to purchase a mattress after only trying if out for a few minutes in the store. If you have a lot of pain, a soft mattress is not for you as you do not get a lot of support. I love the memory foam. Cons: They can be a little on the warm side as they can hold heat. Also, they do not have a flip side to them. You can only use one side. I rotate mine. I see no signs of "sunkeness" at all after 3 years. If you are cold natured, they are great. We love this mattress. We got it at Mattress Firm 3 years ago. We got this mattressed reduced, and it was one of the best investments we have made. We love it. It is very supportive of my aches and pains. Blessings to you and hope you find the right one for you.

Do you sleep on your back? On side?
I cannot sleep on any mattress on my back anymore. I get lower back pain on a tempur-pedic foam, a regular soft top mattress or firm, and I tried laying down for a bit on my son’s sleepnumber but got up aching. When I’m on my back my knees bend backwards - a new problem when menopause took away my estrogen and skin/tendon elasticity. A pillow under my knees or a mattress that lifts my knees work, but neither keep my back from hurting.

I can sleep on my side, with extra pillows for positioning on just about any mattress except those that sag too much in the middle.
I loved our tempur-pedic but my husband got tired of it so we replaced it with a spring mattress with a soft top. Works okay.

I guess you’ve tried side sleeping with a pillow between your knees? Some of the commercial strap-on foam cushions made for this purpose are not made correctly. They don’t separate the knees enough. The separation keeps the back from twisting which is what so many people find painful in the morning.
I also do better if I tuck a pillow under my arm, the one on the high side. But it’s too much trouble to cope with two pillows when I want to turn over, which I do multiple times during the night. I think a long body pillow might work - but it keeps me too separate from my husband - neither of us like that.

Side sleepers - do you have a mattress you like? How about a pillow? I haven’t found a pillow I like much for side sleeping - I’ve tried a bunch.

The foot warmer is built in

Gracias for responding. Sounds heavenly!

Gracias for explaining.
