About the Simba Sleep Hybrid Ultra Mattress
Last checked
The key specification is the medium-firm feel, rated 4 out of 5, rather than a soft, sink-in foam feel or an uncompromising orthopaedic one. Simba’s “Hybrid Ultra” naming places it in the foam-and-spring hybrid camp, so the practical expectation is a comfort surface with some contouring over a more responsive support system than an all-foam mattress. That matters. A medium-firm hybrid under an “Ultra” badge is a mainstream, relatively safe build choice: compared with open-coil mattresses it should feel more controlled under load, but the label itself points to balanced support rather than hotel-bed softness. The comfort story, therefore, has to be read through resistance as much as material. Medium-firm usually gives enough surface compliance for shoulders and hips while keeping the pelvis from dropping too far, which is why it tends to suit mixed side/back use better than very firm traditional sprung beds. The trade-off is obvious: hourglass side sleepers who need deep shoulder and hip immersion may find the support doing its job before the comfort layer has let them in far enough, while back sleepers are more likely to benefit from that flatter, braced feel.
That medium-firm setting is also where the owner feedback makes most sense. Buyers repeatedly describe easier sleep, less morning soreness and strong comfort for back-pain-prone bodies, which lines up with a hybrid mattress intended to combine pressure relief with a more buoyant support core. Couples get a specific positive signal too: partnered owners consistently mention not being disturbed much by movement, a benefit the hybrid format can plausibly deliver when the spring response is individually controlled rather than behaving like a single open-coil sheet. It is not universally firm. The clearest product-side warning is softness: some unhappy owners experience quick sinkage or a dipped feeling, so heavier back sleepers and side sleepers who dislike being held in the mattress may find the medium-firm label over-promises on resistance. The service complaints are separate from sleep feel but still relevant to ownership; low-rated feedback repeatedly flags fulfilment or customer-support frustration, including missing parts on associated bases and slow cancellation help. A recent owner also found the mattress deep enough to raise the bed height and make existing fitted sheets impractical, though that appears more of a sizing nuisance than a broad comfort fault. The strongest case is for average-weight side/back sleepers sharing a bed and wanting cushioning without obvious partner disturbance; very curvy side sleepers are better served by a softer hybrid, while heavier sleepers seeking firmer hold are better matched to firmer pocket-sprung or higher-support hybrid builds.

You spend 8 hours at least every day on your mattress so why not invest in the best The Simba mattress is No. 1 for comfort and quality and for its' hypoallergenic system which was really important on my list as I suffer with dust mite allergies. You can remove the cover on the Simba and wash it, plus I got the hypoallergenic topper for free! Bargain! I believe that you get what you pay for and I don't take any chances when it comes to my sleep health. If you want endless hours of comfortable zzzz's I highly recommend the Ultra Simba mattress. The one drawback I have found is that it is very deep! Making my bed very high and some of my fitted sheets no longer fit as it's so deep, but I think it's worth a few new fitted sheets for quality sleep.
You need this mattress. Best sleep ever.
You just don't want to get out of the bed in the morning. Amazing
Yes, the mattress is not cheap. But what price do you put on your health Getting the Hybrid Ultra Mattress has been life changing for me. Literally within a couple of days, my back and hips have stopped hurting, and I'm sleeping so much better. Really is worth every penny!!
Yes it's expensive; but it I'm sleeping better than ever before. No complaints!
Yep, occasionally (very occasionally) reality is worth the hype. We are a few weeks in and the SiMBA mattress has been a game changer. Bliss!
Wow. What can I say. It's amazing. It's high, it's comfy and I've had an amazing sleep on it since having it (3weeks) Highly recommend
Wow, what a lovely mattress, its the most expensive one I've ever bought but man I think this will last the test of time, I also got the hybrid pillows and between the mattress and pillows its been the best night's sleep I've ever had, even the wife (whos a terrible sleeper due to menopause) agrees how lovely it is keeping her cool, I know it dear but if u could afford it you wouldn't be disappointed
Wow, just wow!! Can't believe how fantastic this mattress is. Having suffered with back pain and interrupted sleep for the past 5 years I thought I was never going to have a good nights sleep again, but along came the Simba and I feel fantastic, fully rested no back ache and no over heating. Thank you Simba
WoW, fabulous bed & mattress! We love it
Wow! Quite possibly the best mattress ever. Have previously had another big brand and this beats that hands down. Very pleased.
Wow! Immediately, we had the best night's sleep from the day was excellently delivered. Each day since our sleep has got better as the bed has now moulded around us. Wish we had bought this months ago!
Wow what a mattress Incredible it is so comfortable I would recommend this to anyone
Wow just wow best nights sleep ever and the pillows are amazing gone from 3 pillows to one the break come with 2 pillows duvet saving over £800 I did not think it would make that much difference to my sleep as have been struggling to sleep for months but it has sruggle to get out of bed now
Wow !!! Amazing !!!! You certainly get what you pay for in this product . The most amazing supportive mattress I've ever owned, slept on just dont know why it had taken me this long to buy one and reap the benefits, never buy anything but Sunna from now on ! And the added benefit was it came with free mattress protection and 200 night sleep warranty and could return at no cost to me if I wasn't happy ! Decay no brainer
Would have given 5 stars but not had it long enough yet. Takes a little getting used to but so far no more pains in the morning and very comfortable to sleep on
Worth the money. Comfortable and good firmness, high quality. A good investment for the future. Had some problems with delivery due to being on the Isle of Wight, consider this before purchase if needing urgently.
Worth the investment. The ultra is the ultimate mattress - the best we have ever owned. Perfect night's sleep every night, some mornings I even wake up in the exact same position I fell asleep in because its so comfy. Having previously suffered with a bad back, I was concerned it might be too firm but the level of support is perfect. Delivery and installation all went well too. I would highly recommend!
worth the investment!
Worth every penny, the most comfortable mattress I've ever had and will never consider a different one from now on, I have the matching pillows and duvet. 100% recommend. Most comfortable sleep you will have. The material is super soft and keeps you cool all night so it's perfect for night sweats!
