Mattress topper that adds a deep, quilted layer of warmth and pressure relief to firm or uneven beds. The MightySoft Mattress Topper brings hotel-style softness with secure corner straps for minimal slipping and cosier nights. Is the 10cm depth the upgrade your mattress needs for noticeably better sleep?

⚡ At a Glance
  • Comfort Level: Deep, plush 10cm microfibre padding for a cloudlike sleeping feel
  • Best for: Sleepers with firm or uneven mattresses seeking extra warmth and pressure relief
  • Not ideal for: Those who prefer a very firm, supportive sleeping surface or medical-grade orthopaedic support

10cm ultra-deep microfibre padding evens out dips and softens firm mattresses. Diamond quilting and elastic corner straps enhance airflow and keep the topper positioned throughout the night.


Even Support and Reduced Pressure – Thanks to 10cm ultra-deep microfibre filling

Thick, dense microfibre filling layers over mattress highs and lows, spreading body weight across a broader surface. Quilted construction keeps the filling distributed evenly to prevent lumps.

Improved alignment eases back and hip tension on older or firmer mattresses, helping sleepers wake with less stiffness. Noticeable pressure relief is most apparent for side and combination sleepers.

Warmer, Cosier Nights – With insulated quilting and breathable microfibre

Diamond quilting traps warm air within the fibre layers while microfibre fibres provide insulation without excessive weight. Breathable stitch patterns support airflow to reduce overheating.

Added insulation keeps sleepers warmer during cold nights while the breathable design helps maintain a comfortable temperature. Ideal for those who wake feeling cold on standard mattresses.

Stable, Smooth Bed Surface – Thanks to secure elastic corner straps

Elastic straps anchor corners to the mattress and the quilted finish minimises bunching by holding the layers flat. Vacuum-sealed packaging allows the topper to expand and settle into place over 24–48 hours.

A secure fit prevents sliding and constant re-tucking, so beds stay neat without nightly adjustments. Faster setup and steady positioning suit busy sleepers and those who move frequently in bed.
