Consider getting a Sleep Number mattress. You can adjust the firmness/softness infinitely to your sleeping pleasure, and if you have a parnter they can adjust theirs seperately from yours. We've had the same one for close to 15 years now and wouldn't have it any other way.

I spent $2,000 on a Queen-size hospital-type bed from Amazon with a 14” four and spring mattress. I love it! The remote control lets me elevate the back, head or knees. It has an anti-snore setting that raises the back just a few degrees and decreases back pain and helps my sinuses drain. (I can’t sleep on my sides when it is up, but I can press one button in the dark and return it to flat.) It even has a vibrator setting with a number or settings. I watch television in bed, and read, and drink coffee. I used to use two big pillows to elevate myself for that. Now the bed does it.

Note that this weighs a total of 350 lbs in the box. I paid about $100 extra for set-up, and that was money well spent. It’s easy to set up, but hard to lift, carry, and turn over. These are really terrific for older people who don’t sleep well or may need to elevate their head or feet. Like us. The king bed has two separate mattresses so they can be raised and lowered separately. But if you like to cuddle at night, the queen is better. If you’ll be sleeping alone the rest of your life, just get a standard size. So much easier to make the bed, and so much more room in your bedroom.

Just replaced a Tuft & Needle Mattress with a King Sizrr Posturpedic Fitm Slab. It was great for about two weeks but back to the store for an exchange for something more comfortable.

I would have bought it online but 60 months INTEREST FREE can’t be beat. In a way I wish I could just cut it out with going for the interest free offers but old habits are hard to break. Ashley in Ocala beat the best online deal I could find by I think a hundred dollars.

The bad part was I couldn’t say no to my wife when she saw a beautiful bedroom set there. It still cost less than the deal we had pending at Babbettes. The quality is not as good but it sure came out better money wise for me. Babettes is the best furniture store I’ve ever dealt with.

We bought from them. We wanted a “traditional“ mattress, not a foam one and we wanted a double-sided one so it could be flipped, which we couldn’t find anywhere else. Good mattress for good price. Great delivery and we paid the fee for them to haul it off. I highly recommend them.

Amazon for half the price, they have all the name brands like Ashley that I got for a steal with a heavy-duty frame for $400.

I bought 2 from The Original Mattress Factory 5 years ago. Best ones I have ever owned!
Still like brand new.

We bought an Avenco king size mattress on Amazon. $500. It comes in a box and when you open the box it basically inflates. It takes 24 to 48 to fully form.
We were skeptical at first but we had friends who had one and you would never know it came out of a box.
Our mattress is very comfortable and comes with a 30 day trial and 10 year warranty.
There are a bunch of these types on line but this brand seemed to be the best.
We went to Mattress Firm and got sticker shock $2000 to $6000. No way!

Original mattress in lady lake us great. They are the only mattress that's double sided. They also added extra framing so when you sit on edge of bed it does not sink. Very comfortable. They take your old bedding for $10. Highly would recommend.

Bought our last mattress from original mattress company. Best mattress I have ever had. They will make it how you want it. Quick delivery.they took the old mattress

Mattress!
 

Saavta all the way!!!!

Same good experience here. They send an email when it is time to turn or flip it. Very important for a mattress to be 2-sided in our experience

Tuft and Needle online store
 

We bought online through "Tuft and Needle" - company in California. Not interspring but we both love the mattress, have slept on it for 5 or 6 years now, king size. They offer trial period and if you do not like it, they will offer refund and/or credit for different choice. They have agencies that will take donations if mattress is not for you rather than return. Had never purchased online nor from them but are pleased with purchase.... another option for you.

We did lie on it at Sams before we ordered it. Very firm than and the same 3 years later.

They delivered it, frame via ups and trucking company for mattress and box spring, but since we had tossed the old one away before moving here nothing to take away. However it was a trucking company so doubt they would have hauled it away.

Overall a very positive experience.

I know you said “innerspring”. But I’d recommend a Sleep Number air mattress. They’re more expensive, but they last forever. We had a king which we finally replaced after 25 years of faultless use. You’ll never come close to that with an innerspring.

Tempur-Pedic
 

You won’t be sorry!! We bought ours in 2006 after my back surgery. There is absolutely no dips or holes in our mattresses after all these years. I am not a small person and looked for a dip after a few years and NONE!! They are just as they were when we bought them. We have 2 twin XL adjustable that are together so we can each adjust to our own liking and each have our own bedding. Hubby is cover hog!!
