Really nice mattress and feels like great quality ,taking a bit of getting used to as my old mattress was so saggy
Great to hear you're loving the quality Rachel! After a saggy old mattress, proper support is a big change for your body, so a wee adjustment period is completely normal. Enjoy - Cam
Bed base and Tasman mattress are awesome. Not too tricky to put together and was amazed that the mattress transformed into a full size mattress from its vacuum pack. Comfortable and great value.
Thanks heaps for taking the time to leave a review! So glad the Tasman's turned out comfy and such great value for you. - Cam
Like sleeping on a cloud team
You're so welcome Keith! So glad you're sleeping so well on the Tasman. - Cam
This is a really great medium-firm mattress. I have a connective tissue disorder and have found that it is the perfect match of comfort and support for my joints, as my previous mattress left me in pain due to tossing and turning and was too firm for my usual odd sleeping positions.
So happy for you Fern, waking up without that tossing-and-turning pain and your joints finally getting the comfort they need is wonderful news! Wishing you many more great sleeps ahead - Cam
Easy to order, delivery was quick, mattress is sweet - job done.
Beauty Chris! Glad the Tasman's got you sorted, enjoy! - Cam
Great value -appreciate the keep it simple' approach
Stoked the Tasman's hit the mark on value for you Chris! - Cam
Product as described and service is great. Quick delivery
Great to hear the service was up to scratch and delivery nice and quick for you Gary, thanks for the review! - Cam
