r/Mattress on Reddit: Sleep Number: why is a Split King more expensive than two Twin XLs?
August 20, 2020 -

I'm thinking of making the jump to a Sleep Number bed and I noticed that two Twin XL mattresses (c2 model) are around $1,200 ($600 each) but a Split King is around $1,600. Aren't these the same things? Shouldn't I just buy two Twin XLs and then get a Split King base? Any insight on this is appreciated!

r/Mattress on Reddit: Adjustable + standard twin xls = king?
April 24, 2023 -

My husband (50m) and I (42f) have been married for almost 15 years and for the past 2 years I have been sleeping almost exclusively in our “spare” room because the bed is more comfortable and there’s more space that way so we BOTH sleep better. My husband admits that we sleep better now but is still not happy about the situation and he is finally willing to look into upgrading to a sleep number type split king (currently have Queen) My husband likes a much firmer mattress than me and has NO interest in using an adjustable frame so he has suggested getting a twin xl adjustable for me and just a standard flat bed from ikea or something for him in order to save money. Is this a thing that would work at all?? Would it even save money?? I have found ZERO information on the internet about it and am frankly getting pretty frustrated.

I have a few notes for you. We were in the same situation recently and had a similar solution. We got two cheap adjustable frames from Amazon and two Sleepnumber C2 mattresses. (everything Twin XL). We put those together inside the footprint of our existing bed. Like the other poster said, this leaves a gap between the mattresses that is kind of strange. The sleepnumber mattresses specifically are very lightweight, so they move more than a standard mattress probably would. I'm currently returning the sleepnumber, and opted for a heavier duty innerspring mattress. i found that I just like the feel of innersprings more than a Sleepnumber at 90-100 percent. If you decide you want Sleepnumber, I would strongly recommend going for the flextop model, and find two twin XL bases someplace else. This would let you adjust the head of your bed independent of your husband's side, but it's still a single mattress, so you won't have a big gap to worry about.

Have you slept on a split king bed before? It’s exactly like sleeping on twin size mattress. So going from a queen to a twin might be a struggle for both of you, since you’re used to sleeping on separate queen mattresses. A one piece king has a lot of room, but split king is a whole different story with the crack that runs down the middle. I was told this several times by people and didn’t understand, but now I do. I just recently went from a king to split king with adjustable bases and wish I wouldn’t have done that. Because it’s like me and my wife are sleeping on different beds, and much smaller beds than we were when it was a one piece king. My mattress is DIY so it’s easy for me to get a king encasement and switch back to a one piece king, which I will eventually do after my wife has our baby (She likes the adjustable base while pregnant). And if she’s pregnant again later I can always switch it back to a split king. If the adjustable base isn’t that important to you, you can try a one piece king mattress that has different firmness levels on each side like the sleeponlatex, sleep number or something similar. If the adjustable base is important and you get the twin xl’s (split king) you can always just get one twinxl adjustable base and a regular base and put them side by side. Just make sure the heights will be the same. There’s no issues in doing something like that. Also look at the Malouf adjustable bases, very nice, with a lot of features and is way cheaper than others I’ve found. I have the S755 in 2 twinxl’s and it was $2,300 delivered from Rest Right Mattress. You have to contact them to get the best price, as their listed prices are higher. Good Luck!

r/sleepnumber on Reddit: Is it worth it?
February 3, 2025 -

My husband and I plan to get a new bed. We’re looking at the split king. My husband prefers hard mattress I like soft. My husband snores like a fog horn and I can’t sleep. My body can’t take the bed we’re in currently and I’ve stumbled upon the sleep number bed. We’ve both said the price is worth it if it truly helps us both sleep and makes our overall living better. Now my question is, is it worth it? We’re looking at just under $10,000 between the mattress, frame, and sheets. Did you find your life/sleep improved with the mattress? Is there something you’d do differently?

Sleep Number Mattress Review: An Honest Assessment | Reviews by Wirecutter
August 27, 2025 - Editor Joanne Chen previously tested an older version and said the mattress reminded her of a “dormitory bed.” For the price, you’re better off with one of our mattress picks, such as the Leesa Sapira Hybrid, a reliable favorite among testers over multiple rounds of testing that is well constructed with sturdy, high-density foams and a generous number of support coils. The c2 is available in twin, twin XL, full, queen, king, and California king sizes. As with the Sleep Number c1, you have the option of selecting either a single or dual air chamber when you purchase a full- or queen-size c2 mattress, but you have to visit a store in person or call the company to select the single-chamber option.
