The bed is lovely in dark green velvet and good quality at a bargain price. It came a couple of weeks after ordering and the cheerful delivery guys were great. They installed everything including the drawers and headboard - worth the extra charge for me. Recommended.

I orders a small double bed for my guest room and it is perfect. Great quality finish and it looks so luxurious in the room. I would highly recommend this company and when the time comes, I'd happily buy from them again.

We're very happy with our product, delivery arrangements and efficiency and helpfulness of man who delivered. (We did find the website did not allow us to buy the stain protection we wanted - forget details. Maybe it was us.) Overall very happy.

We had a great delivery service and great customer service experience. We chose the Kingsford upholstered bed in pink velvet after ordering free samples to decide which fabric worked best for our daughter's bedroom. The bed was so easy to put together!

The Deluxe Bonnell Spring Medium-Firm Mattress is a bonnell mattress with a medium firm feel. Those terms describe this model’s listed construction and comfort rating, making comparison with the other mattresses in the range straightforward.
Available configurations
- Size: Single 3FT, Small Double 4FT, Double 4FT6, King 5FT and Super King 6FT.
Product details
It is offered in Single 3FT, Small Double 4FT, Double 4FT6, King 5FT and Super King 6FT. Select the size that matches your bed frame; the mattress is sold as the selected size only, and a bed frame or headboard is not part of this product. The firmness label is a useful comparison point, although comfort remains personal and can feel different according to body weight and sleep position.
Use the size selector to verify the precise choice and current price before putting it to your basket. The configuration page also presents optional mattress-related services separately; those services are not part of the mattress itself unless deliberately selected.
For ongoing care, use a compatible supportive base, follow the care instructions supplied with the mattress and rotate it only where the product guidance recommends doing so. Measure the intended frame and access route ahead of checkout, particularly for larger UK sizes.
Choosing this configuration
Before choosing a mattress, compare its stated UK dimensions with the specified frame size. Product naming alone is not a substitute for measurement, especially where an existing mattress will be reused. Mattress comfort, construction and depth are separate decisions unless this listing is itself a mattress.
Plan the room from the selected size rather than the staged photography. Floor area, skirting boards, radiators and bedside furniture can affect the usable space around a bed. For taller headboards, also check wall features, sockets, sloping ceilings and the route through stairs and doorways.
Before ordering
Review every picked specification in the basket, as changing size, upholstery, headboard height, button finish or storage can change the final price and availability. Product photography represents the design, while fabric appearance can vary with lighting and screen settings. Dimensions should be checked against the room and delivery route. Only the configuration and any services explicitly selected at checkout form part of the order.
