    • Finally, a "True" Extra Firm Mattress!
Style: Extra Firm Size: Queen
If you’ve been searching for a mattress that actually provides a rock-solid, supportive feel without sagging, the Beautyrest Silver BRS900 Extra Firm is exactly what you need. After years of waking up with lower back pain from mattresses that were too soft, this has been an absolute game-changer for my sleep quality. Here is why this mattress earned 5 stars: Exceptional Firmness: This is a "true" extra firm. You feel supported on top of the mattress rather than sinking into it. It provides that essential spinal alignment that side and back sleepers with back issues often struggle to find. Serious Support System: The 900 Series Pocketed Coil technology is impressive. You can feel the individual support as you move, and the motion isolation is excellent—I don't feel my partner tossing and turning at all. Effective Cooling: I tend to sleep hot, but the DualCool Plus Technology actually works. The moisture-wicking layer keeps the surface temperature regulated, so I’m not waking up sweaty in the middle of the night. High-Quality Edge Support: The BeautyEdge foam encasement is very sturdy. You can sit on the edge of the bed to put on your shoes without feeling like you’re going to slide off, which also maximizes the usable sleeping surface. Durable Build: At 12 inches thick, it feels substantial and well-constructed. It fits standard queen sheets perfectly and has held its shape beautifully since night one. Top Tip: Because this is an Extra Firm model, it may take a week or two for your body to adjust if you’re coming from a softer bed. Stick with it—your back will thank you! If you want a premium, cooling, and incredibly supportive mattress that won't lose its "push-back" feel, this Beautyrest Silver model is a fantastic investment. ... show more

    • Like a rock, Amazon customer service non existent
Style: Extra Firm Size: Full
I feel like a side of beef that Rocky Balboa used for training purposes after one night on this mattress. When they say extra firm, they aren't playing. My previous mattress was supposed to be a 9/10. This one is like 20/10 on the firmness scale. The only use I see for this mattress is if someone wanted to use it as a heavy duty base layer with multiple layers on top. It's VERY supportive, so much that it hurts. Note regarding Amazon: they don't price match, period. I was told to just repurchase and cancel the initial order. They don't let you cancel mattress that aren't "mattress in a box" type deals, period. Despite being told by customer service it would cancel, it didn't. Second one is supposed to be delivered in a week, been trying to cancel it for the last 4 days straight. Just going to have to refuse delivery. Perhaps I can return this heavy hunk of junk with them. I will NEVER buy another large item purchase from Amazon again. Their customer service is total BS. Random Indian chat bots that lie to you and give you fake confirmation numbers and don't do squat. ... show more

    • Great deal
Style: Extra Firm Size: California King
Fabulous! One of the few Cal king 12" memory foam gel top that came in Extra firm on amazon. I lucked out & paid $400 & change. I had to wait approx 2+ weeks for delivery. In that time span the price doubled!!! After reading many reviews & researching memory beds I felt that if you want a medium firmness then buy a firm., and if you want a firm then buy an xtra firm! Be aware that this particular mattress because of the size & exta firmness does not come in a box. Two guys took it off the truck wrapped in plastic & carried it upstairs placing it on my bedframe. They took old mattress away which we had removed for them before they came that morning so we could clean under the bed. All went fast & smooth. Its very comfortable. We wanted xtra firm being its a gel foam & prob wouldn't hold put forever as far as firmness. Judging from the last 3 months im guessing this mattress should last a good 3-4 years. My feeling us that if you truly want a high quality 15+ years mattress, you'll need to spend 3-4k. ... show more
