Looking around for a couple of new mattresses i came across this deal and got a single and king size mattress for £449.98. Dormeo seem a pretty reputable brand and have what look like good guarantees for their products.
I used promo code D10MATT to get an additional 10% off. In addition there is interest free credit available over 6 months for purchase over £399.99 if you qualify. I did and paid 10% deposit (£45) with 6 payments of £67.50.
You also get a free memosan pillow (RRP £39.99) with every mattress.
Their is also 6% Quidco available, unsure about TCB as never use them.
Hope this helps someone.
Code is actually D10MATT not DMATT10
TCB is 6.6%
