About the Sealy PostureLux Forbes Mattress
Last checked
Side comfort is the clearest story in the Forbes: a medium, 3 out of 5 mattress using Sealy’s PostureTech Core Support Plus spring unit, a natural latex layer and two layers of medium foam above it. That combination aims to give pressure relief before the sleeper reaches the spring core, so shoulders and hips get more cushioning than they would on a plain open-coil mattress. A latex layer is a proper upgrade here. It is more responsive and breathable than standard polyurethane foam, and pairing it with twin foam layers gives a deeper comfort stack than many traditional sprung mattresses, though it is still not the same proposition as a pocket-sprung hybrid where each spring moves independently. The PostureTech system is built to firm up progressively under load, which is a sensible, honest way of getting support from a linked spring construction; the trade-off is that movement can travel more across the bed than it would through individually pocketed springs. UniKey edging is the structural feature to notice, because firmer perimeter support usually helps the usable sleep surface feel wider. SilverFresh and ProShield add the hygiene and allergy angle, but they do not change the basic feel: medium cushioning over a supportive Sealy spring base.
Latex and medium foam make most sense for side sleepers, especially average-weight adults who want shoulder and hip pressure softened without sinking into an all-foam feel. Side sleepers get the clearest win. Praise repeatedly centres on comfort that feels supportive rather than hard, with improved sleep and reduced morning soreness cropping up often enough to match the spec’s cushioning-over-spring logic. Back sleepers of average build may still get on with it, but the medium feel is a compromise: it allows some contouring, while people wanting a flatter, firmer lumbar platform may prefer a stronger tension. Several comments also mention an adjustment period, including one case where the delivered mattress felt firmer than remembered and another recent note describing it as thick, around 28cm, which can raise the bed noticeably. Movement is where the promise of calm support weakens: the linked Sealy spring construction can transmit bounce, and the lowest scores include partner disturbance, spring noise during turning and, in the harshest experiences, worsening back pain rather than relief. That sits awkwardly beside the “exceptional support” language, so the customer signal deserves more weight for couples who wake easily. The Forbes suits average-weight side sleepers and mixed back/side sleepers wanting a cushioned Sealy feel; those prioritising low partner disturbance or a firmer back-sleeping platform are better served by the pocket-sprung hybrid tier.

Went for this mattress and it feels comfy but still supportive, and my back doesnt ache as much in the morning. It does get a bit warm at night though.
Comfortable and delivers a quality rest. The medium support works well for all sleep positions.
My experience in store was brilliant, a good hour testing a variety off Mattress to get one that suited me ! it was an adventure! I finally made my choice, Happy now with the quality of steep and the warmth I now experience is Amazing with the Sealy mattress
Great mattress just waiting for new smell to go but know this is normal.
Matteress was on sale and good value . It is a good quality and comfortable but unfortunately i found it too soft for my liking. So exchanging for something firmer. Also it is quite heavy for rotation and deep, so climbing onto it ,but think thats same for most mattresses.
Very comfortable mattress. Very good delivery service. Very helpful staff
The postural mattress is so comfortable just like the shop dreams certainly slide into seventh heaven
My partner and I have enjoyed much improved sleep since our new mattress arrived, reduced aches and pains and seems to be longer periods of sleep throughout the night.
A comfortable bed even for my hair line fracture backbone
I initially popped in to a Dreams store and used the sleep machine to be matched to a few mattresses. There were a number of mattresses that I then tried and managed to narrow it down to two Sealy ones. I chose this one as it felt a little softer, and therefore comfier, than the other one. I have to say that the mattress I received feels a bit firmer than I remember it being in store. However, it is very supportive and comfortable and I am really pleased with the purchase.
Really comfy and look forward to going to bed again now!
Where do I begin Before I bought the Sealy Posture Lux mattress, I had disturbed nights with hip and lower back pain. After sleeping on my new mattress, the pain has gone. Just amazing. I now wake refreshed, having slept for at least 8 hours.I can HIGHLY recommend
Seems like a good quality mattress. Was hoping it would help me get more comfortable with my back aches. Seems quite firm. Not really noticed much difference and it was a lot of money so debating on whether to keep it or change under the 100 day exchange.
Top quality finish Top quality build This Sealy Mattress beats All other brands
The shop experience was great, staff were very helpful, we secretly liked the sleep machine, can we have another go please :-) Ordering and delivery was quick and easy. The mattress seems well made so far and is very comfortable, we are both sleeping better, no aches and pains in the morning like with our last mattress, just make sure you have deep sheets to fit.
Quite possibly the most comfortable mattress I have ever slept on. The quality of sleep that Ive had since it arrived is unmatched. Well worth the money and I would definitely recommend it!
Great mattress! Great service! The Sleepmatch technology helps you find the right mattress in no time. Kevin in Cheltenham was immensely helpful. He offered us coffee and free pillows for good measure.
