So:
£150 - wireless tray, chiclet keyboard and mouse with Razer Turret
£110 - Tray with usb, nothing else with Corsair Lapdog
£160 - mechnical keyboard + wireless tray with Roccat Sova

Any other options?

£5 slab of wood you already have and a £1 bean cushion from pound land stuck to the bottom.

Then use existing kb/mouse

Sorry Razer, please try again.

Having recently gone through the ‘comfy couch’ pain barrier I did look at this.

Ultimately, I found some sanity and have settled on a laptop stand from Ikea @ £20 and can sit in front of my TV at a reasonable distance that your FOV isn't affected for some games and use my existing peripherals.

I think in only extremely small apartments that the above isn't the best solution, even more so if you've got a 10-keyless KB.

For HTPC use I use a wireless keyboard with touchpad (don't like touchpads but the work for basic use), and a 360 controller for gaming. For TV there's the MS remote which I've programmed into my amp's learning-remote for ease. This works beautifully, and allows comfy game streaming via Steam-in-home-streaming (just playing the new Sherlock Holmes this way and it feels lovely). The total bill came to well under 100ukp (25ukp keyboard/touchpad, 30ukp gamepad, 25ukp remote). Keyboard has the advantage of fitting (size-wise) into one of the Ikea cubby holes in the coffee table.

Granted, this doesn't solve FPS keyboard/mouse issues, but an ordinary wireless mouse with a 5ukp “lap tray” (bean-bag base with leather or picture hard surface) should fix that right up. Actually the way the keyboard I use is designed, it'd probably serve as a workable mouse surface if you're only needing WASD and mouse!

I'm riding this particular boat. My monitor died so am using my TV, which is sideways to my desk, so I rotate my chair and plonk a plank (ha) on my lap with my keyboard and mouse. I don't even use a cushion as it'd get too hot, the weight isn't enough to be uncomfortable

for distance gaming i have a logitech g13 pad, which has a perfectly functionable joystick.
it`s easy to program multiple macros, is light, has a screen if you want to monitor things ie; email, computer status- whatever, is backlit with 16.8m colours, has a loong bit of wire, and cost me fifty quid.
also has a built-in wrist-rest.
sorted.

It say Razer… that is enough for me to steer around it… too much brand but way to low quality.

Where is it on sale in the UK? (couldn't see it in the article, Hexus usually say where) unless I missed it?

This has been way, way over engineered..and still doesn't solve the problem - as most of the issue is what you do with the mouse to get a big enough stable esurface area.

I had my PC in my lounge for a few weeks, and I had a wireless keyboard on a laptop “lap tray” like this

Which cost me £5. I brought down my Func solid-backed mousemat and put it on the arm of the sofa. It was perfect and actually a lot more comfortable than my desk. I might switch back one day but for now prefer to keep my gaming separate from my lounge.

Takes one look at the size of the mouse pad. Nope.
