Firm but with a soft top which makes it ideal for us. Very heavy and feels like great quality. We tried it at mattress man and ordered here as cheaper and longer trial period. Would recommend. Ryan. Stanway Colchester, GB. Sat Feb 14 2026

Not too soft and not too firm, the Stella offers medium to firm support, thanks to its mix of body-contouring springs and layers of luxury white fiber fillings.

Very comfortable and sturdy matter. Keep it in the box until you have it in the designated room, i unboxed and it took a few friends to cart it up the stairs. Helps me sleep like a log). Anonymous. Wed Dec 03 2025
