CASHBACK RATE
10% cashback via Awin — what that actually means
AWIN
10%
Base rate — all customers
10% is the rate this merchant publishes in its Awin programme. One product group is excluded at source: the Seel Protection insurance add-on pays no commission on this programme, so cashback is calculated on the rest of the order rather than on that line.

HOW TO CLAIM
How to claim your 10% cashback (3 steps)
1
Click through Tenmomo first
Open Mattress Express using the button on this page. That click sets the Awin tracking — without it, your order cannot be matched to your cashback.
2
Try a code, then check out
Only one code applies per order, so keep whichever is larger on your cart, then pay.
3
Cashback tracks, then credits
Your cashback appears as pending in your Tenmomo account within a few days of the order, then confirms after Mattress Express's validation window on Awin.

HOW WE VERIFY
How we source and verify this page
TM
Verified by the Tenmomo editorial desk
The 10% figure is read from Mattress Express's Awin programme — not estimated, and not copied from a third-party coupon directory.
We list only codes whose terms the brand states and whose presence we confirmed in the network programme, not merely in the feed.
This page carries the date it was last verified, shown above. We revisit it when a review batch reaches it rather than on a fixed schedule — if the date looks old, treat the rate as needing a check on Mattress Express's own site before you rely on it.
Affiliate disclosure: Tenmomo earns a commission when you purchase through the links on this page, at no extra cost to you. This does not influence what we publish — the 10% figure is read straight from Mattress Express's Awin programme, and where that programme leaves something unstated, this page says so instead of filling the gap.
