  1. Julieann

    Exceeded expectations
    Looked around and tested a few beds and mattress types before settling with this product. Although the one bought from thinkassemble.co.uk was an upgrade to the one we looked at in a shop. It is a very substantial and comfortable product which exceeds our expectations. The ordering online was easy and the product delivered exactly as advertised. The delivery guys deserve a mention as the mattress was very heavy but nothing was too much trouble. Very satisfied with this purchase.

  2. DinasO

    Decent quality
    The mattress seems comfortable enough but it arrived with a cut on the underside so is being returned. A bit disappointing but these things happen

  3. Disappointed customers

    Silent night quality issues
    thinkassemble.co.uk had to replace bed frame once and headboard three times due quality issues from silent night who eventually gave me a partial refund

  4. GDJS


    The complete bed package is just what I wanted. However, the Super King matrass weighs a crazy 75kg. This caused major issues for the delivery men to get it safely upstairs to the bedroom. It is also recommended to rotate the matrass regularly which is almost impossible to do due to the excessive weight.

  5. Jake2000

    King Size Divan with drawers
    This is a superb mattress. We opted for the medium firm and are extremely happy with the product. Having visited other big bed stores and tested their beds, this is far superior and a lot cheaper. Equivalent divan and mattresses were nearly 3k! We took a risk as obviously you can’t test the mattress beforehand, but glad we did as it has proved to be an excellent choice. A delayed delivery was the only issue but happy nonetheless.

  6. Snooze

    Too soft
    Not firm enough for me. Gave me back ache from the ‘dips/craters’ on the bed where my mid section would lie. Found the bed retained body heat too. Excellent quality bed though, just not right for me. As always, thinkassemble.co.uk (return policy) absolutely superb. Love, love thinkassemble.co.uk! Will buy an orthapedic bed from thinkassemble.co.uk to replace this one.

  7. Drg62

    Nice comfortable bed but quite high
    A very comfortable bed, with a great balance of softness and support. It is quite high however, and.our bedside cabinets are too low now. Assembly was straightforward but I was surprised that there were only 2 plastic clips to hold the two bed halves together, and they didn’t hold the first time we fitted them, so I used other brackets from our old bed to help hold the bases together. One of the drawers was slightly damaged internally, but I managed to repair that with some strong glue, rather than wait for a replacement. Would be 5 stars if there hadn’t been any issues.

  8. MJC123

    King size bed
    Very comfy mattress and bed base very strong. Drawers are pretty sturdy very happy with my purchase

  9. Cazer

    Very comfortable sleep
    We did our research when purchasing this bed and are very happy with how true the claims and reviews on this mattress are. It is very comfortable and the cooling gel is perfect for my husband and I who are both warm sleepers but have found we don’t get as warm through the night. The frame and headboard are very attractive and we got all this at a great thinkassemble.co.uk price. All around we are very satisfied with this purchase

    Very comfortable. Very high.
    It is a very high bed by the time the mattress is on the base. I’m 6ft and my legs don’t touch the ground about 15 cm above

    Quality and comfort.
    Only had the bed for just over a week, so very early days, but so far I’m very impressed. Very comfortable and sturdy. Quite firm but still luxurious. Getting a great night’s sleep. I will say with the depth of the mattress it really does make it quite high, so you might be too high for your bedside table 🙂. If that doesn’t bother you, everything else is great.

    Very comfortable
    We purchased this bed for our spare bedroom. We have now had guests and ourselves sleep in this bed. The mattress is extremely comfortable. It is heavy and firm – if you like this do not hesitate to buy.
