      A customer photo for Coolflex® Hybrid CHILL Mattress - Great sleep very heavy and thick proper mattress comfy great springs for support. Author: Michael Musgrove. Dated: 2025-10-04
      Trustpilot Star rating Verified

      Very comfortable mattress. Arrived in a box so we were very dubious, had we known it would turn up in a box, we wouldn't have paid the 19 to have it placed in room. Once the mattress expanded we were very pleased with the comfort and quality. Also, it arrived the next day to a remote part of the uk.

      Nice mattress but expected the coolflex to keep you cool at night. Not looking forward to the warmer weather!
