I have the i8 and love it. I regret not getting the adjustable base, though.

So my first "big boy" bed when I moved out was the Sealy Optimum Memory Foam when I first moved out. It was okay, but was too firm and I realized that I should have spent a bit more on the softer model. I worked at Sears in mattresses, and I got the deal of a lifetime for a brand new Tempur-Pedic Cloud Supreme Soft and Ergo Adjustable Base. I got them both for around $500 with tax. That was my taste of high end mattresses, and while it wasn't as soft as I would like, it was the BEST mattress I ever had. It lasted me right up until 2020 (10 years) which it was still fine... I was just convinced by my coworker to get a Sleep Number and use my one time 80% employee discount code for a new mattress. Which 80% off an $8,000 mattress sounded great, and they convinced me that it was better and I would sleep cooler which was my only complaint I had with Tempur. Well... it came and I stupidly said "Haul it away, I'm going to love my new Sleep Number.".... first night... I loathed that mattress. It was just a glorified air mattress, and that's all I could feel. It even felt firmer than my old Tempur. I regretted my choice, and was basically stuck with it. Sleep Number did give me a mattress topper to make my i8 even softer, but it still felt like an air mattress and just wasn't comfortable. When I got a job at Casper Mattress, after a few months of working I got a free Original Mattress. Which felt better than Sleep Number, but was firmer than I liked. So I used the topper Sleep Number gave me to at least make it work. Still wasn't perfect, but at least I could turn on my side without having to lift myself up and feel the whole mattress move. When Casper did a contest for a free Wave Hybrid Snow, I went rabid. I knew my luck was awful and that I would lose, but I had a plan. I would sell so much for the next two months that Casper would feel bad and give me the Wave Hybrid Snow. I legit told every customer that there's a contest, and even if they don't want to buy a mattress but wanted to buy a pillow or sheet set, not to do it online but come see me. I was the number one sales person for those two months.... and I did lose the contest. My manager did the math, I had an 87% chance of winning, and I lost to someone who literally had one ticket in the raffle. However, my plan worked. Casper gave me the Wave Hybrid Snow because one region didn't have anyone sell enough to even be entered in the raffle. So they gave me the one that would have been given to that region. The Wave Hybrid Snow was better, cooler and more comfortable to lay on. However, a year and a half later I had to do a warranty claim. Which Casper kind of put up a fight with because they said I won the mattress, so it was free. I pushed back, saying that it was a horrible defect and I was using their Adjustable Base Max (when I won the mattress I upgraded my adjustable base as well for the massage) and that the whole front end of the mattress caved in. Eventually, they replaced it. When I got a job working at Tempur-Pedic. I was toying with the idea of just upgrading to the LuxeBreeze Soft and the new ProSmart Adjustable Base. However, I didn't really have a reason and the Wave Hybrid Snow was fine. I didn't want to be one of those people who upgrade their mattress every year or two. Well, someone ran a red light a t-boned me. Totaled my Mustang, sent me to the ER from the scene of the accident, and I was in horrible condition. When I got home, my body just HATED my mattress. What was fine before just hurt, it felt like I was on a rock. I was in so much pain, that any pressure on my sides just hurt. So that was my excuse to just upgrade for the LuxeBreeze Soft. I have had my LuxeBreeze Soft since 2024 and it's been amazing. I don't wake up hot, I don't wake up in pain, I can fall asleep quicker than I ever did before. So long story short, yes... a really great mattress is worth it.

Nah, I just like helping people. I started right after high school, and I just liked working with people to find what works best for them. If I really wanted a job for the discounts, I would have got something in the home theater market because I love my Sony TVs… but I feel like I replace those just as easily because something better came out. 😂 I had the Sony A8G OLED, loved it… then Sony came out with a QD-OLED the A95K Master Series and I immediately upgraded to that. However, I really didn’t like that I constantly had to switch the HDMI settings to Enhanced Dolby Vision to Enhanced VRR. So when the newer A95L dropped… I upgraded to that. Now that Sony is coming out with an RGB MiniLED… I’m curious how good that performs… because I’ve been wanting to go from a 65” to a 75”. 😂

Sleep Number bed changed my life with extreme back pain! I recommend going to the store and trying one out. I purchased the i8 with adjustable base. Zero gravity setting gave me back my life.

Same. We purchased one last year and it's been a game changer. People scoff at their price, and yes they are expensive. $6K+ for a bed seems crazy until you experience good rest. We have a split top and it can auto raise if one of us starts to snore or whatever, and it really does work. I sleep better on a firm bed and my wife sleeps better on a soft bed. We each have our side adjusted how we like it. We went through 3 of the other name brand foam beds over the last 5 years trying to find one we liked. We could just never get comfortable.

I’m not a Sleep Number shill, I promise. I bought one eighteen months ago with an adjustable frame and I’ve never slept better. I wake in the same position that I fell asleep in with no pressure point aches or pain and head up so no more GERD wake ups. They are not cheap, but I got what I paid for.
