Amazon's Prime Big Deal Days runs for 48 hours on Monday 6 and Tuesday 7 October 2026. It is the autumn version of Prime Day, and the deals are for Prime members only.
The trouble with any sale is telling a genuine deal from a dressed-up one. A "was" price on a deal badge is not always the price the thing actually sold for last month. So we recorded the Amazon UK price of every pick below on 24 September 2026, and checked each one again on 6 October with the event live.
Event update: what we saw on 6 October
We checked all 13 picks on Amazon UK on the afternoon of 6 October. Eight are on a Prime deal and one more has dropped without a badge. Two have not moved, one is slightly dearer, and one is out of stock new.
The four best deals
- SIHOO M18: £121.12, down from £194.99. That is £73.87 off, or 38% below the price we recorded. It is the chair we said to watch most closely, and it is the best deal on this page.
- Logitech MX Ergo S: £55.99, down from £84.99. £29 off, a 34% cut on the newer, quieter trackball.
- FlexiSpot E1 Plus: £113.04, down from £139.99. We said anything around £110 to £120 would make it the cheapest way into a reliable electric desk. It has landed right there.
- Logitech MX Vertical: £47.49, down from £60.95. £13.46 off, 22% below the September price.
Real, but modest
- Logitech ERGO K860: £84.99, down from £99.99. A £15 cut with no deal badge, and it does not appear to need Prime.
- Logitech Lift: £32.99, down from £38.99. We said a deal needed to take it into the low £30s to be worth waiting for. It has.
- FlexiSpot 160 x 80 cm One Piece: £185.72, down from £195.49. The badge says 23% off its £239.99 list price. Against what it cost in September, the saving is £9.77.
- Logitech MX Keys S: £79.99, down from £84.99. £5 off.
- BONTEC Dual Monitor Arm: £24.67, down from £25.97. £1.30 off.
No deal
- The SIHOO Doro C300 is still £259.99 and the FlexiSpot anti-fatigue mat is still £48.99.
- The Kensington Duo Gel set is £30.83, up 66p.
- The Logitech Wave Keys in Graphite is out of stock new. The only offer we saw was a used one at £42.99.
Amazon releases new deals through the event, so prices can change again before it ends on 7 October.
How to shop Prime Big Deal Days without overpaying
- Check against the price before the event, not the "was" price. The September prices in this guide are what you would have paid without any event running.
- A badge can overstate the saving. The FlexiSpot One Piece and BONTEC arm were already below list price in September, so the real saving is the gap to that price, not to the crossed-out figure.
- Lightning deals sell out. Short, limited-quantity deals often run out before the timer does. If a desk or chair you want drops into one, do not overthink it.
- You need Prime. The deal prices only show to Prime members. A free trial counts, so if you only want Prime for this, you can cancel afterwards.
- Delivery on big items can slip. Desks and chairs ship from third-party warehouses and can take a week or more during the event. Order early if you need it by a certain date.
Standing desks
FlexiSpot 160 x 80 cm One Piece: £185.72 (was £195.49 on 24 Sep)
A Prime deal, but a small one: £9.77 below the September price. It is a big 160 x 80 cm desktop that arrives attached to the frame, so assembly takes much less time than a two-part desk. It has room for two monitors and a laptop side by side, plus memory presets on the control panel. Still a good desk at a good price, just not a dramatic deal.

FlexiSpot E1 Plus (120 x 60 cm): £113.04 (was £139.99 on 24 Sep)
A starter desk that won't let you down, and now £26.95 cheaper. A 120 x 60 cm maple-effect top on a white frame, with four memory presets and an 80 kg load rating. That is plenty for one monitor and a laptop. At £113.04 it is the cheapest reliable electric desk we list.
If you are standing for longer than half an hour at a time, the FlexiSpot anti-fatigue mat is worth adding. It has no deal and is still £48.99.

Office chairs
SIHOO M18: £121.12 (was £194.99 on 24 Sep)
The standout deal. The M18 is one of the most-reviewed ergonomic mesh chairs on Amazon UK, with over 1,900 ratings averaging 4.4 stars. It has adjustable lumbar support, a headrest and a mesh back that stays cool. At £121.12 it is £73.87 below what it cost two weeks ago.
SIHOO Doro C300: £259.99 (no change)
A step up, with dynamic lumbar support that moves with you rather than a fixed pad, plus soft 3D armrests. It has no deal. With the M18 now £138 cheaper, the Doro is hard to justify during the event unless you specifically want the dynamic lumbar.

Keyboards
Logitech MX Keys S: £79.99 (was £84.99 on 24 Sep)
£5 cheaper. It is a low-profile backlit keyboard with a full number pad. It switches between three devices at the press of a key. If you type all day and do not want a split layout, this is the one, though the saving is small.
Logitech Wave Keys: out of stock new (was £43.99 on 24 Sep)
A gentle wave-shaped layout with a cushioned palm rest. It is ergonomic without the learning curve of a fully split board. On 6 October the Graphite version was not available new from Amazon, and the only offer was a used one at £42.99. Check the listing, as stock on this one tends to come back.
Logitech ERGO K860: £84.99 (was £99.99 on 24 Sep)
A split, curved keyboard with a built-in wrist rest, for people with wrist or forearm pain. We said this was the one where a deal makes the biggest difference. It is £15 cheaper, with no deal badge on the listing.
Our best keyboard for wrist pain guide covers these in more depth.
Mice and trackballs
Logitech Lift: £32.99 (was £38.99 on 24 Sep)
The Lift is a vertical mouse sized for small to medium hands, and it has more than 10,000 reviews on Amazon UK. We said a deal needed to take it into the low £30s to be worth waiting for, and £32.99 does that.
Logitech MX Vertical: £47.49 (was £60.95 on 24 Sep)
The larger vertical mouse, for medium to large hands, with nearly 14,000 reviews. We said to wait for a deal rather than pay full price. This is that deal: £13.46 off.
Logitech MX Ergo S: £55.99 (was £84.99 on 24 Sep)
A thumb trackball with an adjustable tilt, for people who want to stop moving their arm altogether. It is the newer, quieter version of the original MX Ergo, and at £29 off it is the best peripheral deal here.
Monitor arms and accessories
BONTEC Dual Monitor Arm: £24.67 (was £25.97 on 24 Sep)
Nearly 39,000 reviews. It holds two 13 to 27 inch screens on gas springs and frees up most of your desk. The Prime deal takes £1.30 off a price that was already a bargain.

Kensington Duo Gel Wrist Rest Set: £30.83 (was £30.17 on 24 Sep)
A matching keyboard and mouse gel wrist rest pair. It is a cheap fix if your wrists ache by the end of the day. No deal, and 66p dearer than in September.

Frequently asked questions
When is Prime Big Deal Days 2026? Monday 6 and Tuesday 7 October 2026, running for 48 hours in the UK.
Do I need Prime to get the deals? Yes. Deal prices only show to Prime members. A Prime free trial counts if you are eligible for one.
Is Prime Big Deal Days as good as Black Friday for office furniture? Often it is similar. Big brands tend to hold their deepest cuts for Black Friday, but standing desk and chair brands sold mostly through Amazon, like FlexiSpot and SIHOO, often discount in both. The SIHOO M18 at £121.12 is a clear low against its September price, and there is no guarantee it will be cheaper in November.
How do I know if a deal is real? Compare the deal price with the price before the event, which is what the table above is for, rather than the "was" price on the deal badge.
Prices were checked on Amazon UK on 24 September and 6 October 2026 and will change. Event prices are for Prime members. DeskMinded earns a commission on qualifying purchases made through links on this page, at no extra cost to you.
